DETERMINATION METHOD FOR DRIVE FORCE TO BE REQUESTED FOR HYBRID VEHICLE, AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2022/241720

Kind Code:

A1

Abstract:

A determination method for a drive force to be requested for a hybrid vehicle, and an apparatus. The determination method comprises the following steps: obtaining a gear state, a current vehicle speed, a current gas pedal degree of engagement, and drive force mapping information of a vehicle, the drive force mapping information indicating a correspondence relationship between vehicle speed, gas pedal degree of engagement, and drive force (S201); if the gear state is such that the vehicle is not in park gear or neutral gear, obtaining a driving mode and altitude data of the vehicle (S202); and if the altitude data is less than a preset altitude, determining a drive force to be requested for the vehicle on the basis of the current vehicle speed, the current gas pedal degree of engagement, the driving mode, and the drive force mapping information (S203). In the present determination method, different methods are able to be utilized to obtain a drive force to be requested on the basis of different driving mode, altitude data, and gear state situations, and a current vehicle speed and a current gas pedal degree of engagement can also be directly converted into a traction force requirement for the entire vehicle.
