摘要： Provided are a control method and system for a hybrid electric vehicle after a battery failure and a hybrid electric vehicle. The control method includes: after monitoring that a failure occurs in a power battery, judging whether the failure is a specific type of failure or not, the specific type of failure being a battery failure under which a motor of a hybrid electric vehicle is capable of conducting voltage control (S402); if so, setting a relay of the power battery to be disengaged after a preset time (S404); before the relay is disengaged, coordinating and controlling the power battery, an engine, a transmission and the motor of the hybrid electric vehicle to enable operation states thereof to meet a preset voltage control entering condition (S406); and controlling the motor to enter into a voltage control mode (S408). The motor is allowed to enter into voltage control smoothly and operate stably, thus avoiding problems of overtemperature of a battery, serious voltage fluctuation and the like caused by direct voltage control on the motor after a power battery failure.

摘要： A method and a device for determining a requested driving force of a hybrid vehicle is disclosed in the present invention. The method for determination includes the following steps: acquiring a gear status, a current vehicle velocity, a current accelerator pedal opening and driving force mapping information of the vehicle, wherein the driving force mapping information represents a corresponding relationship among the vehicle velocity, the accelerator pedal opening and the driving force; acquiring altitude data and a drive mode of the vehicle if the gear status is that the vehicle is not in a parking gear or a neutral gear; determining a requested driving force of the vehicle based on the current vehicle velocity, the current accelerator pedal opening, the drive mode and the driving force mapping information if the altitude data is less than the preset altitude. Different methods can be used for the method for determination to obtain the requested driving force based on different drive modes, altitude data and gear status, and the current vehicle velocity and the current accelerator pedal opening can be directly convert into a demand for vehicle traction in the present invention.

摘要： Embodiments of the present application disclose a method, a device, an electronic equipment and a storage medium for controlling engine stop. The method includes acquiring current state information and operation parameter information of an engine, the current state information includes a starting state, and the operation parameter information includes revolution speed information, start duration information, coolant temperature information and torque information of the engine. If the current state information is the starting state, and the revolution speed information, the start duration information, the coolant temperature information and the torque information meet a first preset stop condition corresponding to the starting state, the engine is controlled to be in the stopped state. Based on the embodiments of the present application, excessively long starting time and excessively low revolution speed of the engine can be prevented, damages of hardware equipment such as a starting motor and a dual-mass flywheel can be avoided, and safety and reliability of the system can be improved.
