The present disclosure discloses a dynamic control system and method for power of a vehicle. The system includes: an electronic horizon system, configured to obtain slope information and to send the slope information to a power controller; an accelerator pedal, configured to output accelerator pedal depth information to the power controller; and the power controller, configured to fit a power output curve for entering a next slope, and to control an engine or a motor of the vehicle to output a torque according to the power output curve. The present disclosure can generate the power output curve for a next road segment in real time.

Dynamic control system and method for power of vehicle

Provided are a method for predicting an energy consumption-recovery ratio of a new energy vehicle, and an energy saving control method and system for the new energy vehicle. The method includes: (1) acquiring, by means of an electronic horizon system, geographic information data of a position that is K meters ahead on a road from a current position of the new energy vehicle; (2) compiling statistics on speed information during the process of the new energy vehicle traveling S meters to reach the current position, values of K and S being the same; and (3) taking the geographic information data and the speed information as input vectors, inputting the same into a trained artificial neural network, and outputting a predicted energy consumption-recovery ratio. The present disclosure can optimize energy control over the vehicle, improve the utilization rate of electrical energy, and increase the traveling mileage.

The present disclosure relates to a method for controlling a following distance based on terrains, a terminal device, and a storage medium. The method includes the following steps: S1. dynamically acquiring a slope θ of a current driving road; S2. calculating a dynamic following distance d based on the slope θ; S3. determining whether d is within an acceptable following distance range [d1, d2], if d is within the range, controlling the following distance of a vehicle to be d, otherwise proceeding to step S4; and S4. if d is smaller than d1, controlling the following distance of the vehicle to be d1; and if d is greater than d2, controlling the following distance to be d2. With the method of the present disclosure, the following distance can be automatically and dynamically adjusted based on the terrains to achieve the consistency of energy saving and safety.

Method for controlling following distance based on terrains, terminal device, and storage medium

Disclosed in the present disclosure are a lift axle control method for a vehicle and a lift axle control system for a vehicle, wherein the method comprises the following steps: step 1) acquiring a load M of the vehicle; step 2) judging whether it needs to lower the lift axle according to the load, and if so, controlling the vehicle to lower the lift axle, and entering into step 3); otherwise, returning to step 1); step 3) calculating an optimal position of lifting the lift axle, controlling the vehicle to lift the lift axle at the optimal position, and entering into step 4); step 4) calculating an optimal position to lower the lift axle, controlling the vehicle to lower the lift axle at the optimal position, and then returning to step 3). The method of the present disclosure can reduce the damage to the road surface and achieve the economy of fuel consumption during running of the vehicle.
