Abstract
A vehicle braking energy recovering method includes obtaining current location information of a vehicle, determining a current road scenario based on the current location information of the vehicle, determining the current road scenario based on a mapping relationship between a road scenario and a weight, determining a safe distance and a safe speed of the vehicle based on the weight, determining a target torque based on the safe distance and the safe speed of the vehicle, and controlling, based on the target torque, a motor of the vehicle to recover braking energy.
Claims20
A vehicle braking control method, comprising:
- obtaining inside information of a first vehicle;
- obtaining outside information of the first vehicle, wherein the outside information comprises first information from sensors on the first vehicle and second information from an internet of vehicles (IoV), and wherein the second information comprises a status of a traffic light and a distance between the traffic light and the first vehicle;
- and
- performing regenerative braking control based on the inside information and the outside information by controlling a motor to recover braking energy based on a speed of the vehicle, the status, and the distance.
A vehicle braking control apparatus, comprising:
- a memory configured to store instructions;
- and
- a processor coupled to the memory and configured to execute the instructions, which when executed by the processor, cause the vehicle braking control apparatus to be configured to:
- obtain inside information of a first vehicle;
- obtain outside information of the first vehicle, wherein the outside information comprises first information from sensors on the first vehicle and second information from an internet of vehicles (IoV), wherein the second information comprises a status of a traffic light and a distance between the traffic light and the first vehicle;
- and
- perform regenerative braking control based on the inside information and the outside information by controlling a motor to recover braking energy based on a speed of the first vehicle, the status, and the distance.
A computer program product comprising instructions that are stored on a computer-readable medium and that, when executed by a processor, cause a vehicle braking control apparatus to:
- obtain inside information of a first vehicle;
- obtain outside information of the first vehicle, wherein the outside information comprises first information from sensors on the first vehicle and second information from an internet of vehicles (IoV), wherein the second information comprises a status of a traffic light and a distance between the traffic light and the first vehicle;
- and
- perform regenerative braking control based on the inside information and the outside information by controlling a motor to recover braking energy based on a speed of the vehicle, the status, and the distance.
A vehicle comprising:
- one or more sensors configured to obtain first information;
- and
- a processor coupled to the one or more sensors and configured to:
- obtain inside information of a first vehicle;
- obtain outside information of the first vehicle, wherein the outside information comprises the first information and second information from an internet of vehicles (IoV),
- wherein the second information comprises a status of a traffic light and a distance between the traffic light and the first vehicle;
- and
- perform regenerative braking control based on the inside information and the outside information by controlling a motor to recover braking energy based on a speed of the vehicle, the status, and the distance.
