The present disclosure relates to a method of controlling gear selection in a transmission of a vehicle in response to a directional shift requested by an operator and to a control system for controlling gear selection to manage directional shifts in vehicles, from a first direct to a second direction (e.g. forward to reverse). The method compares the current transmission output speed with a predetermined direction shift threshold transmission output speed. If the current transmission output speed is less than or equal to the predetermined direction shift threshold transmission output speed, the transmission is caused to execute a direction shift from the initial first direction gear to the same second direction gear, or a next highest second direction gear if there is no second direction gear which corresponds to the initial first direction gear. If the current transmission output speed is greater than the predetermined direction shift threshold transmission output speed, the direction shift is inhibited until the current transmission output speed slows to less than or equal to the predetermined direction shift threshold transmission output speed.

A method of controlling an engine and a transmission of a hybrid vehicle includes steps of: determining whether the vehicle starts, determining an engine RPM and a gear stage of a transmission if the vehicle has started, determining whether the engine RPM has reached an engine speed control point, determining an engine target RPM and an engine target RPM slope of the vehicle when it is determined that the engine RPM has reached the engine speed control point, controlling the engine RPM of the vehicle to follow the engine target RPM and the engine target RPM slope, determining whether the engine RPM has slipped compared to the target engine RPM, and performing PID control to follow the engine target RPM if the engine RPM slips compared to the engine target RPM.

The present disclosure relates to the technical field of vehicles, and particularly to a vehicle control method and apparatus, a storage medium and a vehicle. The method includes: acquiring a pressure of a brake master cylinder and an opening degree of an accelerator pedal; when the pressure of the brake master cylinder is greater than a first preset pressure threshold, the opening degree of the accelerator pedal is no less than a first preset opening degree threshold, and a moment when the pressure of the brake master cylinder is greater than the first preset pressure threshold is earlier than a moment when the opening degree of the accelerator pedal is no less than the first preset opening degree threshold, controlling the vehicle to enter an activated state of a launch starting function; and when the vehicle is in the activated state, controlling an engine of the vehicle to output a target torque. Thus, a driver enables the vehicle to enter the activated state of the launch starting function before starting by operating a brake pedal and the accelerator pedal at the same time, and also enables the vehicle to provide a torque output according to a state of the accelerator pedal while being in a brake state, thus enabling the vehicle to start quickly with greater power, reducing an acceleration time and realizing launch starting.
