Curve control method for new energy vehicle

Abstract

The invention discloses a curve control method for new energy vehicles. An electric motor on a new energy vehicle is used for providing compensation force which is in the opposite direction of drivingforce to reduce the magnitude of the driving force; to keep the magnitude of the combined force of the vehicle unchanged can avoid the malaise brought by sudden acceleration; and the speed of the vehicle can be controlled according to the turning angle and speed, the leaning of human bodies caused by turning can be reduced, and the safety and comfort of passengers can be further improved.

Description

technical field [0001] The invention relates to a control method for a new energy vehicle, in particular to a control method for the new energy vehicle when turning on a curve. Background technique [0002] When the car is turning in a curve, the direction and magnitude of the resultant force of the vehicle will change due to a lateral steering force. When the steering force is greater, the direction of the resultant force will deviate from the direction of the front of the car, resulting in a strong Drift feeling, that is, passengers will deflect in the opposite direction of the turning direction due to inertia, which will give passengers discomfort, and even cause personal injury in severe cases. The best way to solve the above problems is to slow down and turn the steering wheel slowly, but this is Braking is required to slow down, which not only wastes kinetic energy, but also prolongs the driving time. [0003] For new energy vehicles, especially new energy buses, due ...

Problems solved by technology

[0002] When the car is turning on a curve, the direction and magnitude of the resultant force of the vehicle will change due to a lateral steering force. When the steering force is greater, the direction of the resultant force will deviate from the direction of the front of the car, resulting in a strong Drift feeling, that is, passengers will deflect in the opposite direction of the turning direction due to inertia, which will give passengers discomfort, and even cause personal injury in serious cases. The best way to solve the above problems is to slow down and turn the steering wheel slowly, but this is Need to brake to slow down, which not only wastes kinetic energy, but also prolongs driving time

[0003] For new energy vehicles, especially new energy buses, due to the large number of passengers on board, and some passengers do not even have any grasping or leaning positions, the addition of steering force when the vehicle turns quickly increases the resultant force of the vehicle. For passengers, it will cause a large sense of sudden acceleration and direction deviation, which will cause passengers to tilt or even fall down. Therefore, in order to ensure the safety and comfort of passengers, it is necessary to solve the above problems
