Abstract

The invention provides a truck retardance control system. The truck retardance control system comprises a power supply, a truck body controller, a brake controller, an engine control system, a retarder control system, a combined instrument, a truck speed sensor, an engine rotation speed sensor, a brake pedal sensor, an engine brake switch and an exhaust auxiliary brake switch. As the truck speed sensor and the engine rotation speed sensor can collect current truck speed and engine rotation speed and one or more brake modes with good comprehensive performances exist within each truck speed and engine rotation speed range, the brake controller can determine the current appropriate brake mode according to truck speed information and engine rotation speed information, which are monitored from a CAN bus, and a pre-marked brake mode comparison relation and recommend the current appropriate brake mode to a driver when the driver steps on a brake pedal; therefore, the driver is effectively instructed to select the appropriate brake mode to improve the brake effect of the current vehicle, enhance the vehicle fuel economy and prolong the part service life.

Description

technical field [0001] The invention relates to the technical field of electronic control, in particular to a truck retarding control system. Background technique [0002] Modern logistics has higher and higher requirements for timeliness. The speed of vehicles is getting faster and higher, and the load is getting higher and higher. The safety performance of the braking system is becoming more and more important. When driving, especially on long downhill roads, frequent braking is harmful to the The braking system of a vehicle presents great challenges, and once the brakes fail due to thermal degradation, the consequences can be severe. In order to solve the above problems, in the prior art, auxiliary braking is performed through exhaust auxiliary braking, engine braking, and retarder braking. [0003] However, different auxiliary braking methods have different braking effects, vehicle fuel economy and component life under different working conditions. Therefore, how to mak...
