Embodiment Construction
[0050] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, so they are only examples, and should not be used to limit the protection scope of the present invention.
[0051] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application shall have the usual meanings understood by those skilled in the art to which the present invention belongs.
[0052]When the pure electric tractor needs to slow down or stop when driving on the tunnel, it can only be achieved by downshifting or pulling the hand brake, or even pressing the emergency stop button; the foot brake equipped with the vehicle cannot be linked with the drive system. , when the foot brake signal is valid, the drive system is still outputting power; thus there is b...

The invention belongs to the technical field of pure electric tractors, and provides a foot brake control method and device for a pure electric tractor, equipment and a medium. The method comprises the steps that vehicle state information is obtained, wherein the vehicle state information comprises a driving motor rotating speed signal, a foot brake pedal signal and a current gear signal; and if the vehicle state information meets the linkage control condition, the vehicle executes linkage control of braking and driving. By the adoption of the technical scheme, the state information of the vehicle is obtained, after the vehicle meets the preset linkage control condition, the vehicle executes linkage control over braking and driving, the linkage control condition limits the vehicle to execute linkage of braking and driving under certain fixed state information, and a better speed reduction effect of braking is achieved.
Description
technical field [0001] The invention relates to the technical field of pure electric tractors, in particular to a foot brake control method, device, equipment and medium of pure electric tractors. Background technique [0002] With the vigorous development of urban rail transit, more and more rail tractors are put into use. How to ensure that the tractors can decelerate more conveniently in the driving process has become the focus of safe use, especially in the driving process. Slopes, under the working conditions that require frequent speed control, make the cooperation between braking and driving more demanding during driving. [0003] At present, the main problem is that when driving on the tunnel and encountering the need to slow down or stop, it can only be achieved by downshifting or pulling the handbrake, or even pressing the emergency stop button; the foot brake equipped with the vehicle cannot be linked with the drive system Control, when the foot brake signal is v...
