Problems solved by technology

[0002] At present, most of the heavy-duty vehicles in China are equipped with retarders (including hydraulic retarders and eddy current retarders), which solve the safety problems of heavy-duty vehicles such as brake system heating and brake failure caused by long-term driving braking.
However, most of the retarder devices in the prior art are independent closed devices, and their control methods are mostly decentralized single-system independent control, which cannot be controlled globally from the perspectives of vehicle powertrain management and braking system integration, so there are functional Single, poor security, complex operation and other issues

Embodiment Construction

[0014] The present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0015] figure 1 It is a flowchart of the control method of the present invention.

[0016] The present invention includes conventional five-speed negative torque control function; adjustable constant speed control function; intelligent slow braking function; slow braking intelligent release function; retarder brake handle self-diagnosis function, etc., specifically includes the following functions and step:

[0017] 1. Detect whether the intelligent retarder switch is activated: After the vehicle retarder function is turned on, first detect whether the intelligent retarder switch is activated. When the intelligent retarder switch is activated, the system enters the intelligent braking mode.

[0018] The intelligent braking mode refers to realizing the intelligent braking function of the vehicle through the intelligent braking switch. In this pro...

Abstract

The invention discloses a heavy-duty car retarder integrated control method. The method comprises the following steps: 1, after the finished car retarder function is started, firstly, detecting whether an intelligent retardance switch is activated or not, if yes, entering the intelligent retardance function, and if not, entering step 2; 2, detecting whether a retarder handle is broken down or not, if not, entering the handle control function, and if yes, entering step 4; 3, when the situation that retardance braking intelligent termination conditions are met is detected, entering step 4; 4, closing the finished car retarder function. According to the heavy-duty car retarder integrated control method, integrated control is conducted from the angles of finished car power assembly management, braking system integration and the like so that the intelligentization, safety, convenience and the like of the retarder functions can be expanded, and by means of the method, a heavy-duty car retarder can operate in a more effective, more convenient and faster, more intelligent and safer mode.
