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

Embodiment approach

[0019] The new energy vehicle in this embodiment is a hybrid vehicle, including an engine, an electric motor, and a power supply. The engine and the electric motor drive the hybrid vehicle together, and the power supply provides the electric energy required for the operation of the electric motor. , the hybrid electric vehicle can also include a generator, the generator is connected to the engine, and the generator is driven by the engine to generate electricity and store electric energy in the power source, which can be a power battery or a supercapacitor and other vehicle power supplies with storage functions.

[0020] When the hybrid vehicle is turning in a curve, the on-board control device obtains the size of the current vehicle driving force according to the depth value of the gas pedal of the hybrid vehicle, and then calculates the size of the current steering force according to the rotation angle and speed of the steering gear , control the electric motor to provide a ...

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 ...
