1, the automatic parking concepts
automatic parking system is an automatic function for you to pull the hand brake, and then activate the feature, such as when parking and other traffic lights, equivalent to not pull the hand brake, this feature is particularly suitable for frequent start on the downhill and when parking.
electronic parking brake is electronic parking brake system. Electronic parking brake system (EPB: Electrical Park Brake) refers to the integration of the braking function long after the temporary traffic during braking and parking together and the parking brake by an electronic control technology. Electronic parking brake hand brake is implemented by an electronic control technology. It works the same as with the mechanical hand brake, by friction brakes are generated by the brake pads to control the parking brake, but the control mode from the previous mechanical handbrake lever into an electronic button. Extending from the electronic handbrake parking from basic functions to automatic parking function AUTO HOLD. Use AUTO HOLD automatic parking function technology, allows the driver to brake when the vehicle does not need a long time to stop. And the case of start automatic electronic parking brake, to avoid unnecessary glide vehicle, simply means that the vehicle will not slip.
automatic parking brake system – advantages
traditional handbrake need to rely upon a hill start the driver manually release the hand brake or throttle skilled, be comfortable with the clutch start. AUTO HOLD while the automatic parking function gives accurate parking force by the gradient sensor by the controller, at startup, the control unit through a parking information calculated by the distance sensor of the clutch, the clutch kneading speed sensor, an accelerator pedal sensor, etc. provided, when the driving force is greater than the parking brake is automatically released when the running resistance, so that the car can be smoothly started. Even in peacetime Sese go urban driving, as long as you AUTO HOLD function is enabled, it will start the appropriate automatic parking function. Smart AUTO HOLD automatic parking function allows the vehicle to start waiting for a red light or on a four-wheeled parking brake when going downhill, even in the D range or N range, you need not have foot brake or hand brake, the car is always in Stationary state. To release the stationary state, the throttle can simply tap the brakes are released. This configuration is for those who oftenReally practical in the city stop and go car owners, but also reduce the number of unnecessary accidents caused by people due to the careless.
against the cold – parking heater
parking heater: Benefits heater and passenger vehicles in addition to windscreen defrosting and heating car interior, but also effectively improve automotive cold start performance, improved cold undesirable emissions vehicles
and the vehicle occupant heater benefits in addition to defrost windshield, automotive internal heating, but also effectively improve the cold start performance cars, car cooler improve undesirable emissions [123 ] driving friends have experienced the winter morning feeling just entering the cabin – biting cold. If they catch just under the snow, the windshield is full of snow and ice cover on a worse plight. Ignition engines hurry off after a few minutes away from the normal operating temperature of the engine is very far, then the engine can not timely access to good working condition, and exhaust emissions seriously overweight. These are the problems we face with the car in the winter. However, if your car is equipped with a parking heater, it is not the case.
vehicle heater in the 1950s appeared. At that time in order to enhance the comfort of the bus, the German company Webasto heater developed a separate converter as bus matching. After continuous innovation and development, today’s heater system has covered all models, and the volume has been getting smaller and smaller, and more advanced technology. Today’s heater also has a remote control and preset function, you can set up automatic or remote control warm-up ahead of time at any time. No need to start the vehicle engine, the heater is to launch its own dedicated computer radiators, heating the cabin and engine. Until you open the door, comfortable, cozy warmth immediately greeted. The main parking heater member can be divided into the heater body, circulating pumps, metering pumps, the intake muffler, exhaust muffler, timers and remote control.
2, parking heater works and working process
The heater is mounted in series with the engine cooling circuit. First, by a remote control or a timer activation signal to the ECU, the meteringPumps pump oil from a tank and fuel in pulses hit the metal felt before the combustion chamber, ignition pencil heated to 900 ℃, the fine oil droplets splash vaporized and ignited, the flame transfer thermal energy to the engine cooling liquid. When reaching the preset starting temperature, the blower air conditioner starts to operate, the hot air blown into the vehicle. Heated while the engine is warm coolant.
When the engine cold start why warm
cold start of the engine needs more concentrated gas mixture, the more the fuel consumption. At the same time in order to play a role in catalytic converters also require heating, but also require more heat emission, to achieve the desired operating temperature. Therefore, up to 80% of hydrocarbon emissions occur within two minutes after the start of the engine. Tests show that after 30 minutes using a parking heater, carbon monoxide can be generated in the engine cold start, hydrocarbons, nitrogen oxides and other emissions by 67%! Further, since the engine preheating obtained, the degree of wear is greatly reduced, according to the information in the case of proof 40 ℃ deg.] C and 80, the former for the latter engine wear 5-fold, at minus 20 ℃ imagined to start the vehicle engine the extent of harm.
The heater which consumes fuel and electricity
The heater generates heat by consuming fuel, but also consume some battery power. TT series current Webasto heater can be automatically adjusted according to the temperature rise and fall in the case of three operating power, usually a 20-minute start, fuel consumption is about 0.2 liters, the start fuel for a fuel-efficient car idling state heat than the engine much more.
3, the advantages of the heater
quite a few advantages of the heater, such as avoiding cold starting the engine, the engine protection, reducing engine exhaust emissions and fuel consumption, vehicle interior heating, no ice on the windshield, plagued by frost, greatly improving visibility. The heater in the summer can bring us many benefits: in the summer simply set about the remote control or timer, heater becomes summer ventilation device which can make the car blower outside air input to the interior of the car, keep the car ventilation, thus effectively reducing the air conditioning load.
the German market, a survey showed: 76 percent of consumers are willing to buy direct from the factory with a car heater car, 33 percent of consumers it is natural to think that the parking heater is an effective means to improve the comfort of the winter, there are 15 the percentage of people willing to install parking heaters in the next few years. It seems heater in the Nordic market has been widely recognized.
car heater in the country is not a new thing, many northern buses, buses have already installed the heater, just do not pay attention to us. In the car field, with the introduction of foreign models (currently heater has been widely selected European car manufacturers), Webasto heater has been produced vehicle as the Audi A6 and A4 optional equipment of the factory, as factory optional equipment models is also increasing, such as the Mercedes-Benz E-class, BMW 5 Series, BMW 3 Series and so on, but still mainly used in high-end cars.
Automatic parking lever: 1, the parking brake action:
A, after the vehicle stopped, it braking action.
b, during emergency braking, which act together with the service brake.
2, the use of the handbrake method:
Here, (Great Wall pickup) parking brake lever to illustrate its use: the handbrake two forms, one for the front-a is a side-mounted, despite their different positions, but their function is the same. Front braking action when pulled back, side-mounted braking action on the pull-up. Front released when necessary to press down the button in the handle, the handle will turn right, while not turn pushed forward, pushed to close in the end, and then turn the handle to the left on the line level. When releasing side-mounted, the handle must press the button into the front end, and then placed in the end of the handle is released the brake.
