Engineering vehicle brake control method and engineering vehicle brake control device

Abstract

The invention discloses a brake control method of an engineering vehicle and a brake control device of the engineering vehicle. The method comprises the steps: judging whether a brake instruction is obtained or not; under the condition that the braking instruction is obtained, obtaining the vehicle speed information and load information; generating a corresponding brake control strategy based on the vehicle speed information and the load information, wherein the brake control strategy acts on at least one brake mechanism; and controlling the at least one brake mechanism to execute corresponding brake operation based on the brake control strategy. All the brake mechanisms of the engineering vehicle are uniformly controlled, and in the actual brake process, one or more corresponding brake mechanisms are automatically controlled to execute brake operation according to the actual brake requirement, so the brake operation of a driver is greatly simplified, misoperation is effectively avoided, the output brake force is reasonably distributed, the problem of sudden braking caused by overlarge braking force is avoided, user experience is improved, effective braking is guaranteed, and braking safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a braking control method of an engineering vehicle, a braking control device of an engineering vehicle, a computer-readable storage medium and an engineering vehicle. Background technique [0002] Engineering vehicles are mainly used in engineering construction scenarios. During operation, engineering vehicles mainly include two operating states: heavy-load operation and light-load operation. [0003] In the light-load running state, the weight of the engineering vehicle is relatively light, and at this time the driver can drive the engineering vehicle at a higher speed. At this time, once the engineering vehicle needs to brake, it is necessary to ensure that the engineering vehicle has sufficient The braking force and braking stability have higher requirements on the braking capacity of engineering vehicles. On the other hand, in the heavy-duty running state, the weig...

Problems solved by technology

[0004] In the prior art, in order to ensure that engineering vehicles have sufficient braking capacity, multiple braking mechanisms are configured on engineering vehicles, such as hydraulic retarding braking mechanisms, electric eddy current retarding braking mechanisms, engine-assisted braking mechanisms, etc. mechanism, brake master cylinder, etc. However, in the actual application process, each of the above-mentioned brake mechanisms is controlled by a separate brake switch or brake handle, and it is impossible for the driver to control each brake during the driving process of the engineering vehicle. All braking mechanisms are used reasonably, so on the one hand, it causes a waste of braking capacity and resources; on the other hand, the driver may make misoperation during driving, which will cause additional safety risks.
