In emergency situations, 90% of car drivers lack decisiveness when applying the brakes. The brake assist system is designed for this situation. It can detect the vehicle's driving speed from the speed at which the driver depresses the brake pedal. When the driver quickly depresses the brake pedal in an emergency, but the pedaling force is insufficient, this system will assist and increase the braking force to the maximum in less than 1 second, shortening the time required for emergency braking. braking distance.
1. Exhaust brake
The exhaust brake is a type of auxiliary brake. The exhaust brake is actually a valve that blocks the engine's exhaust system so that the engine cannot exhaust properly. Therefore, the engine becomes a compressor, which is used to absorb the kinetic energy of the car's movement and reduce the car's driving speed. Cars used in some mountainous or plateau mountainous areas, as well as heavy-duty vehicles and buses used in the north, are often equipped with exhaust brakes.
Using this exhaust brake when going downhill has the following advantages:
●It can reduce the burden on the service brake and prevent the brake drum from malfunctioning due to excessive temperature.
● Extend the service life of the service brake system.
●It can prevent slipping. In the case of slippery snowy roads, if the driving brake is used, it is easy to cause the wheels to slip sideways. When using exhaust brake. The vehicle speed is slowly reduced and the braking is balanced to prevent the wheels from slipping. Exhaust brake is a relatively economical and effective auxiliary braking device.
2. Downhill retarder
Using exhaust brakes when going down long slopes can reduce the workload of the service brakes to a certain extent, thereby reducing the chance of thermal degradation and extending their service life. However, for heavy-duty vehicles used in mountainous areas or mines, exhaust braking has limited effect, so hydraulic or electric downhill retarder is often used. These two types are also auxiliary braking devices.
