Problems solved by technology

[0003] When the vehicle is running, if the brake hydraulic pipeline fails, emergency parking by parking is a feasible emergency measure, but the linearity of the parking brake force is poor, and the vehicle decelerates suddenly, which is easy to damage the surrounding vehicles and surrounding vehicles. Pedestrians pose danger, and vehicles driving at high speeds are likely to cause safety accidents

Abstract

The invention relates to the technical field of vehicle safety, in particular to an EPB and danger warning lamp combined control method and system in vehicle running. According to the system, in the vehicle driving process, when the time for pulling an EPB switch exceeds t1, after an ESP controller and an EPB controller are arbitrated, an ESP module is called firstly to build the pressure of a hydraulic pipeline, and vehicle speed reduction is conducted; and if the hydraulic pipeline fails, the ESP controller and the EPB controller request the EPB calipers to brake the motor after arbitration, and meanwhile, a request is sent to turn on a brake lamp, an EPB switch indicator lamp and a danger warning lamp to provide warning information for a driver and surrounding vehicles. After the switch is pulled to brake and stop, the danger warning lamp is kept, and the EPB switch indicator lamp continues to flicker until the driver manually turns off the EPB switch. The control process is carried out automatically, operation links of a driver in emergency are reduced, and driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a combined control method and system of EPB and hazard warning lights during vehicle running. Background technique [0002] EPB (Electrical Park Brake), EPB controls the parking brake through electronic circuits. The function is the same as the mechanical lever handbrake. There is no need to manually turn off the electronic handbrake when starting, and the electronic handbrake will be automatically turned off when the accelerator is stepped on to start. The electronic parking brake system is an electronic handbrake button that replaces the traditional lever handbrake. It is safer than the traditional lever handbrake, and will not change the braking effect due to the driver's strength, turning the traditional lever handbrake into a button within reach. [0003] When the vehicle is running, if the brake hydraulic pipeline fails, emergency parking by parking is a feasible ...
