Abstract: A method and an apparatus for vehicle control, a storage medium, an electronic device, and a computer program are provided. The method is applicable to a vehicle and includes: acquiring a target deceleration, if the vehicle is traveling on a road section; and performing the braking energy recovery according to the target deceleration, if the vehicle receives a brake instruction and triggers the braking energy recovery. For each vehicle of a plurality of vehicles, the target deceleration is determined by a plurality of history decelerations of each vehicle when traveling on the road section and triggering a braking energy recovery.

Abstract: A driving mode control method, apparatus, device, program and storage medium, which relates to the technical field of electronic control, and is for a control platform, the method includes: acquiring a location information sent by a target vehicle, wherein the location information comprises a target location; determining a status data of at least one sample vehicle pre-stored by the control platform based on the target location, wherein the sample vehicle is a vehicle which has travelled through the target location; determining a target driving mode based on the status data of the sample vehicle, and sending the target driving mode to the target vehicle, such that the target vehicle travels in the target driving mode. This disclosure enables the target vehicle to travel in the target driving mode. The driver needs not to manually switch the driving mode, and the accuracy and convenience of controlling the drive mode are improved.

Abstract: A method and a device for controlling mode switching of a hybrid electric vehicle, and a vehicle is provided, and belongs to the field of hybrid electric vehicles. The method includes: performing, if the drive state information indicates that a current drive mode of the hybrid electric vehicle is a forward mode of a non-hybrid drive and in a case that a current speed reaches a speed limit, a pre-gear operation when a transmission gear of the hybrid electric vehicle is a neutral gear, to switch the transmission gear from the neutral gear to a second gear. The technical solution provided by the embodiments of the present disclosure can make the hybrid electric vehicle unable to switch to the hybrid drive mode due to the limitation of the ability of synchronizer on gear shifting when driving at a high speed.
