Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] The invention provides a power safety control method for a pneumatic braking vehicle, such as figure 1 As shown, including the start control strategy and the driving control strategy, the start control strategy includes the following steps:

[0022] 1) Obtain the brake pressure value of the vehicle brake system when the vehicle is started, and judge whether the brake pressure value is less than the lower limit of the starting pressure value.

[0023] The control method of the present invention can be realized by a pneumatic brake vehicle power safety control device, the device includes a controller and a pressure sensor for detecting the brake air pressure of the vehicle brake system, the input end of the controller is connected to the pressure sensor, the The pressure sensor may be an existing gas pressure sensor in the vehicle braking system. When ...

Abstract

The invention relates to the technical field of vehicle braking, in particular to an air brake vehicle power safety control method and device. The device comprises a controller and a pressure sensor used for detecting braking air pressure of a vehicle braking system. The input end of the controller is connected with the pressure sensor. When a vehicle is started, the controller obtains a braking air pressure value of the vehicle braking system, when it is judged that the braking air pressure value is smaller than the lower limit of a starting air pressure value, the vehicle braking system is controlled to be inflated, the whole vehicle is controlled not to respond to a whole vehicle accelerator signal and / or a vehicle gear signal until the braking air pressure value is no smaller than thelower limit of the starting air pressure value, power safety control over the air brake vehicle is achieved, and the problem that when the vehicle braking air pressure is low, power is still output, the vehicle is controlled to operate, and thus severe wear of brake linings is caused is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a method and device for controlling power safety of pneumatic braking vehicles. Background technique [0002] In existing air pressure braking vehicles, when the vehicle is started, the instrument pressure signal is lower than the maximum air pressure set by the pressure sensor, the air pump starts to work, and the driver observes the pressure value of the instrument. After about 1 minute, the pressure pointer reaches the starting pressure of 0.6Mpa. Loosen the air brake valve, shift gears and step on the accelerator to start. This method is normal start. However, when the air pressure value does not reach the starting air pressure of 0.6Mpa, the gear will be put on and the accelerator pedal will be stepped on. At this time, the power output will cause the wheels to generate torque and wear the brake linings, which will affect the service life of the brakes. Contents of...
