20220397087 · 2022-12-15 ·

The present application disclosed a a method and a device for controlling start-stop of a vehicle, a vehicle and an electronic apparatus. The method includes steps of: acquiring a first start-stop instruction, and determining a first start-stop type of the vehicle according to the first start-stop instruction; acquiring a second start-stop instruction, and determining a second start-stop type of the vehicle according to the second start-stop instruction; and performing start-stop controlling on an engine according to priorities of the first start-stop type and the second start-stop type. Therefore, the method can actively control the start-stop of the engine according to the priority of the start-stop type, which can well respond to the driving intention of the driver, the driving experience is improved, the start-stop time of the engine is saved, and the fuel consumption of the vehicle is greatly reduced, and the driving safety of the vehicle and the personal safety of the driver and passengers are guaranteed.

Methods and system for stopping an engine

Systems and methods for stopping an engine of a vehicle are described. In one example, the method anticipates when an engine is expected to stop and modifies engine operation so that less fuel is in the engine's intake ports when the engine is stopped so that the fuel may not escape the engine when the engine is restarted.

Start/stop device for initiating an automatic activation process of an automatically deactivated drive machine

A start/stop device initiates an automatic activation process of an automatically deactivated drive machine of a motor vehicle, in particular of a motor vehicle with an automatic transmission. The drive machine can be automatically deactivated when the motor vehicle is traveling, and the automatically deactivated drive machine can be activated on the basis of driver actions. The start/stop device is configured to initiate an automatic activation of the drive machine which is automatically deactivated when the motor vehicle is traveling on the basis of a detected drive dynamic desired by the driver.

METHODS AND SYSTEM FOR STARTING AN ENGINE

Systems and methods for starting an engine of a hybrid vehicle are described. In one example, the method selects one or more electric machines to start an engine. The method may reference a data structure, such as a matrix or table, and the matrix or table outputs which of the one or more electric machines is applied to start the engine.

Control system for vehicle

A control system is intended for a vehicle having an automatic stop-restart function that automatically stops an engine when a predetermined automatic stop condition is satisfied and restarts the engine when a predetermined restart condition is satisfied during an automatic engine stop. The control system has an automatic stop restricting function that, when the host vehicle is located in a first predetermined area before a temporary stop sign, prohibits an automatic stop of the engine. When a preceding vehicle is located in the first predetermined area, the automatic stop restricting function is deactivated.

Method and system for a hybrid power control in a vehicle

Methods and systems for improving fuel economy and reducing emissions of a vehicle with an electric motor, an engine, an energy storage device, and a controller are disclosed. The method includes obtaining current state information including a current hybrid control surface, and determining a target hybrid control surface for the vehicle based on the current state information.

A vehicle control method is provided such that when a host vehicle is stopped at a front of a vehicle line of vehicles in accordance with a stop signal of a traffic light at an intersection, the engine is stopped by using an idle stop control. When either a left-turn or a right-turn will be made after the traffic light changes to a go signal, a presence or an absence of a traveling body, which is stopped on a side of or behind the host vehicle in a direction from which the host vehicle is turning, is detected during the stop signal. Upon determining the traveling body is stopped on the side of host vehicle, restarting of the engine is placed on standby even when the traffic light turns to the go signal, and the engine is restarted in accordance with a behavior of the traveling body.

Method and system for vehicle stop/start control

Methods and systems are presented for improving performance of a vehicle operating in a cruise control mode where a controller adjusts torque output from a vehicle to maintain vehicle speed within a desired range. The methods and systems include adapting a vehicle dynamics model and a vehicle fuel consumption map that provide input to nonlinear model predictive controller.

Control method and control device for automated vehicle
