  • Patent number: 12071041
    Abstract: A charging system includes a charging controller and an estimated completion time deriver. The charging controller adjusts a temperature of an on-board battery with a heater so that the temperature of the battery is kept equal to or higher than a predetermined temperature. The battery is chargeable with electric power supplied from a power supply outside a vehicle. The charging controller charges the battery with charging power excluding temperature adjustment power consumed by the heater from permitted suppliable power supplied from the power supply to the vehicle. The estimated completion time deriver derives an estimated completion time based on an estimated value of the permitted suppliable power in a future and an estimated value of the temperature adjustment power that is derived based on an estimated value of an outside air temperature in the future. The estimated completion time is a time when charging is predicted to complete.

    Abstract: An antilock control method for a braking system of a vehicle has at least the following steps: upon the presence of a brake request signal, outputting a brake control signal and building up a brake pressure by a braking medium at a wheel brake of a vehicle wheel, measuring a wheel speed of the vehicle wheel to be braked, and determining a wheel slip of the vehicle wheel, upon meeting a first traction criterion or a locking tendency of the vehicle wheel, activating a wheel drive unit and applying a wheel drive torque on the vehicle wheel to increase the wheel circumferential velocity and to reduce the wheel slip until a second traction criterion is met. The brake force introduced in the wheel brake is controlled as a function of the wheel slip by releasing the brake pressure upon satisfying a first traction criterion.

  • Patent number: 11958365
    Abstract: The present disclosure discloses a method for dual-motor control on an electric vehicle based on adaptive dynamic programming. First, total torque required is calculated based on obtained data information of the electric vehicle under various driving conditions, and offline training is conducted on an execution network and an evaluation network. Then total torque is dynamically distributed for two motors of the electric vehicle under various driving conditions to obtain an efficiency MAP database. Afterwards, iteration and online learning are conducted on the execution network and the evaluation network based on data information of the electric vehicle under different driving conditions that is obtained in real time, so as to find an optimal control law for the electric vehicle under a real-time driving condition. In this way, the dual-motor control on the electric vehicle is optimized.

  • Patent number: 11951874
    Abstract: A vehicle driving system that can suppress a difference in effect of vehicle attitude control between the cases where a friction braking force is applied and not applied, is provided. The system includes a rotating electric machine, a battery, a steering apparatus, a steering angle sensor, a brake actuator that applies a friction braking force, a friction braking force sensor, and a controller that sets a deceleration torque based on a steering speed detected by the steering angle sensor and controls the rotating electric machine to apply the deceleration torque to a front wheel of the vehicle, thereby executing a vehicle attitude control. When the friction braking force is applied to the wheels by the brake actuator during the vehicle attitude control, if the friction braking force is large, the controller corrects the deceleration torque to a larger value than when the friction braking force is small.
