A method for providing engine start information for a hybrid electric vehicle includes determining a likelihood of engine start for each of a plurality of reasons for engine start, and displaying a reason for engine start having a highest likelihood of engine start from among the plurality of reasons for engine start and engine start information including the highest likelihood of engine start in consideration of a type of at least one reason for engine start and a level of the likelihood of engine start.

Provided are an automobile chassis integration control method and system. The control method includes the steps that: a cooperative control unit receives a first engine torque output by an EMS, a first engine torque limiting request output by a four-drive controller, a second engine torque limiting request output by an ESP, and a third engine torque limiting request output by a TCU from a CAN bus respectively; and the cooperative control unit cooperatively controls the first engine torque limiting request, the second engine torque limiting request, the third engine torque limiting request, and the first engine torque, and outputs a second engine torque as an engine execution torque.

Controls for improved drivability of a vehicle equipped with start/stop logic are disclosed. A nominal control stop for the internal combustion engine of the vehicle is disabled or prevented from occurring in response to a vehicle mass and route grade indicating a roll back condition for the vehicle exists if the nominal control stop for the engine were to take place.

An engine start-stop control method and device for a hybrid electric vehicle, and a hybrid electric vehicle belong to the technical field of vehicles. The method includes: obtaining a target parameter or a target signal, which is engine start-stop related, of the hybrid electric vehicle; determining, according to the target parameter or target signal, whether an engine start-stop related event occurs; if so, determining a level of the engine start-stop related event; and performing engine start-stop control according to the engine start-stop related event and the level thereof; wherein the engine start-stop related event includes at least one of the following: an energy management related start-stop event, a driving behavior related start-stop event, an engine state related start-stop event, an external controller request start-stop event, and other condition related start-stop events. The operating efficiency of the vehicle and the user experience are improved.

The invention relates to a method of controlling a vehicle powertrain including determining that a performance feature associated with the powertrain is outside of a desired performance range. A plurality of operation parameters that are associated with the powertrain are identified that have a relationship to the performance feature. An adjustment is automatically made to at least one of the identified operation parameters to thereby bring the performance feature closer to the desired performance range. Preferably, the relationship comprises a mathematical model that corresponds to how the operation parameters influence whether the performance feature is within the desired performance range, the method further comprising identifying an actuator failure associated with the powertrain; determining at least one of the operation parameters corresponding to the actuator failure; determining a value of the corresponding operation parameter that is indicative of the actuator failure; and using the determined value as a fixed value for the corresponding operation parameter in the mathematical model.
