Problems solved by technology

If the vehicle is driving at a high speed, especially in overtaking or climbing conditions, the occasional braking signal will cause the vehicle to fail to drive according to the driver's preset, which will not only lead to failure of overtaking or climbing, but may also cause serious damage to the driver and the vehicle. serious impact on the safety of

Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0041] figure 1 It is a flow chart of the vehicle control method provided by the embodiment of the present invention. Specifically, please refer to figure 1 , the method includes:

[0042] Step 10, obtaining the vehicle speed change rate of the vehicle.

[0043] Specifically, when a braking operation is performed, the vehicle usually changes from a state of high driving speed to a state of low driving speed, and the rate of change of the vehicle speed is usually relatively large. When no braking operation is p...

Abstract

The invention discloses a vehicle control method and device, a vehicle. The vehicle control method comprises the following steps: acquiring a vehicle speed change rate of the vehicle; Comparing a magnitude of the vehicle speed change rate and a preset value of the vehicle speed change rate; Controlling the vehicle to enter a brake priority mode if the vehicle speed change rate is greater than or equal to the vehicle speed change rate preset value; Wherein the brake priority mode is to respond to the brake signal preferentially when a brake signal is received with an accelerator opening degree.By judging the relationship between the vehicle speed change rate and the preset value of the vehicle speed change rate and executing the brake signal only when the vehicle speed change rate is greater than or equal to the preset value of the vehicle speed change rate, the vehicle control method provided in this embodiment can avoid the influence of the accidental brake signal on the normal running of the vehicle and ensure the safety of the driver and the vehicle.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobiles, and in particular to a vehicle control method and device, and a vehicle. Background technique [0002] At present, commercial vehicles are equipped with a brake switch, and the ECU controls the vehicle engine to stop fuel injection and exit cruise by responding to the brake signal provided by the brake switch. [0003] However, in the prior art, due to reasons such as the quality of the brake switch and the installation position, the brake signal is often set when the driver does not step on the brake during the running of the vehicle, resulting in sporadic brake signals. Even with the throttle opening, the ECU usually responds to the brake signal first, causing the throttle to be temporarily disabled and causing the vehicle to lose power. [0004] In the case that the driver has no intention of braking, the occasional braking signal will also have a certain impact on d...
