Problems solved by technology

[0003] However, in electric vehicles, in order to improve energy utilization and increase cruising range, braking energy recovery and coasting energy recovery have become the standard configuration of electric vehicles. When electric vehicles enter coasting energy recovery, the vehicle is in a deceleration state. The pedal is not pressed, according to the existing brake light control strategy, the brake light will not light up, so the vehicle behind may keep the speed unchanged, resulting in a rear-end collision accident

Embodiment Construction

[0041] It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. In view of the technical problem solved by the present invention, it is necessary to determine whether the current vehicle speed is deceleration, and all the following embodiments involve acceleration, which is a negative value, so it will be described here.

[0042] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0043] An embodiment of the present invention provides a vehicle brake light control method, such as figure 1 As shown, the following steps may be included:

[0044] S100, identifying the road condition on which the vehicle is currently driving.

[0045] For example, if figure 2 As shown, the identification of the road conditions on which the vehicle is currently traveling may include the following steps:

Abstract

The invention relates to the technical field of electric vehicle control, and provides a vehicle brake lamp control method, device and system and a machine readable storage medium. The vehicle brake lamp control method comprises the steps that the road surface condition of a vehicle currently running is recognized; when the road surface of the vehicle currently running is a bumpy road surface andthe current acceleration of the vehicle is larger than a preset bumpy road surface acceleration threshold value A, a vehicle brake lamp is controlled to be turned on, and otherwise, the vehicle brakelamp is controlled to be turned off; and when the road surface of the vehicle currently running is a non-bumpy road surface and the current acceleration of the vehicle is larger than a preset non-bumpy road surface acceleration threshold value B, the vehicle brake lamp is controlled to be turned on, and otherwise, the vehicle brake lamp is controlled to be turned off. According to the vehicle brake lamp control method, device and system and the machine readable storage medium, for the sliding energy recovery scene of the electric vehicle, the situation that when sliding energy is recovered, due to the fact that the vehicle speed is reduced, a rear vehicle does not obtain a signal in time, deceleration or braking is conducted, and finally traffic accidents are caused is avoided.

Description

technical field [0001] The present invention relates to the technical field of vehicle electrical control, in particular to a vehicle brake light control method, device and system and a readable storage medium thereof. Background technique [0002] As we all know, the vehicle reminds the rear vehicles of the current speed of the vehicle through the brake light signal, so that the distance between the front and rear vehicles can be kept within a safe range. The existing brake light control strategy controls the lighting of the vehicle brake light by collecting the signal of the brake pedal. When the brake pedal is stepped on, the brake light is on, and when the brake pedal is not stepped on, the brake light is off. . [0003] However, in electric vehicles, in order to improve energy utilization and increase cruising range, braking energy recovery and coasting energy recovery have become the standard configuration of electric vehicles. When electric vehicles enter coasting en...
