Abstract
An automobile brake control method comprises: obtaining wheel rotation speed sensor information of an automobile within the current measurement period; and when the wheel rotation speed sensor information satisfies a preset condition, allowing the automobile to enter an aquaplane safety logic control mode, and after an ABS operates, allowing the ABS to exit front axle control and merely control a rear axle so that a driver takes over automobile control, until the next measurement period.
Claims9
An automobile brake control method based on an anti-lock braking system (ABS), applied to an aquaplaning condition, comprising:
- acquiring information of a wheel speed sensor of an automobile in a current detection period based on an angular velocity signal collected by the wheel speed sensor on a wheel of the automobile;
- allowing the automobile enter an aquaplaning safety logic control mode when the information of the wheel speed sensor satisfies preset conditions, and allowing the ABS to exit a front axle control and to only control a rear axle until a next detection period;
- automatically turning on a red warning light of an automobile instrument by collecting a pressing signal generated by a brake pedal being pressed on by the driver, after the automobile enters the aquaplaning safety logic control mode in the current detection period;
- and
- allowing the automobile exit to the aquaplaning safety logic control mode, allowing the ABS to control the front axle, and further turning off the red warning light of the automobile instrument after the next detection period arrives, in response to that an acquired information of the wheel speed sensor in the next detection period does not satisfy the preset conditions.
An automobile brake control system based on an anti-lock braking system (ABS), deploy in an automobile, comprising:
- a processor;
- and
- a memory for storing program executable by the processor;
- wherein the processor is configured to perform an automobile brake control method based on an anti-lock braking system, applied to an aquaplaning condition, wherein the automobile brake control method comprises:
- acquiring information of a wheel speed sensor of an automobile in a current detection period based on an angular velocity signal collected by the wheel speed sensor on a wheel of the automobile;
- and
- allowing the automobile enter an aquaplaning safety logic control mode when the information of the wheel speed sensor satisfies preset conditions, and allowing the ABS to exit a front axle control and to only control a rear axle until a next detection period;
- automatically turning on a red warning light of an automobile instrument by collecting a pressing signal generated by a brake pedal being pressed on by the driver, after the automobile enters the aquaplaning safety logic control mode in the current detection period;
- and
- allowing the automobile exit to the aquaplaning safety logic control mode, allowing the ABS to control the front axle, and further turning off the red warning light of the automobile instrument after the next detection period arrives, in response to that an acquired information of the wheel speed sensor in the next detection period does not satisfy the preset conditions.
A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of an automobile brake control system based on an anti-lock braking system (ABS), causes the automobile brake control system to perform an automobile brake control method based on the anti-lock braking system, applied to an aquaplaning condition, the method comprising:
- acquiring information of a wheel speed sensor of an automobile in a current detection period based on an angular velocity signal collected by the wheel speed sensor on a wheel of the automobile;
- and
- allowing the automobile enter an aquaplaning safety logic control mode when the information of the wheel speed sensor satisfies preset conditions, and allowing the ABS to exit a front axle control and to only control a rear axle until a next detection period;
- automatically turning on a red warning light of an automobile instrument by collecting a pressing signal generated by a brake pedal being pressed on by the driver, after the automobile enters the aquaplaning safety logic control mode in the current detection period;
- and
- allowing the automobile exit to the aquaplaning safety logic control mode, allowing the ABS to control the front axle, and further turning off the red warning light of the automobile instrument after the next detection period arrives, in response to that an acquired information of the wheel speed sensor in the next detection period does not satisfy the preset conditions.
