A driving force control device for a vehicle is provided, which includes a motor, an engine, and a controller. The controller sets a target torque of the vehicle corresponding to accelerator operation, and distributes a target engine torque according to a distribution rule defined beforehand, based on the target torque of the vehicle, and outputs a control signal corresponding to the target engine torque to the engine. The controller estimates a future amount of intake air to a cylinder based on the target engine torque, and estimates a torque of the engine in the future based on the estimated future amount of intake air. The controller sets a target motor torque based on the estimated torque of the engine so that the target torque of the vehicle is achieved in the future, and outputs a control signal corresponding to the target motor torque to the motor.

A system may include a vehicle controller, comprising: a hardware platform, comprising a processor and a memory; and instructions encoded within the memory to: provide an autonomous vehicle control module with at least L4 vehicle control capability; select a semi-autonomous operating mode that uses a subset of the L4 vehicle control capability; and operate a vehicle in the semi-autonomous operating mode.

A vehicle control device includes a driving force setting unit and a motor controller. The driving force setting unit sets a first requested driving force on the basis of accelerator opening and makes dulling processing on it to set a second requested driving force. The motor controller controls a motor driving force on the basis of the second requested driving force. The motor controller executes a slip control on the condition that the driving wheel slips on accelerated travel. The slip control includes controlling the motor driving force on the basis of a limited driving force smaller than the second requested driving force. In stopping the slip control, the motor controller compares the first requested driving force and the motor driving force. On the condition that the former is smaller than the latter, the motor controller controls the motor driving force on the basis of the first requested driving force.

When a driver is not in pedal erroneous operation inducing situation and a rate of change in an operation amount of an accelerator pedal is equal to or greater than a first erroneous operation determination threshold value, a driving assistance apparatus determines that operation of the accelerator pedal is erroneous operation. When the driver is in the pedal erroneous operation inducing situation and the rate of change in the operation amount of the accelerator pedal is equal to or greater than a second erroneous operation determination threshold value, the riving assistance apparatus determines that the operation of the accelerator pedal is the erroneous operation, and the second erroneous operation determination threshold value is smaller than the first erroneous operation determination threshold value.

A method and system for controlling clutch friction elements of an automatic transmission is provided. The method includes retrieving information about shift clutches from a data storage unit and acquiring information required to predict a temperature of a friction element for each shift clutch, deriving a predicted temperature value of a friction element for each shift clutch by using the information about the shift clutches and the information required to predict the temperature of the friction element, predicting whether or not overheating occurs for each shift clutch by comparing the derived predicted temperature value of the friction element for each shift clutch with an allowable temperature set for each shift clutch, and determining a target shift stage while avoiding the overheating clutch with a predicted temperature value exceeding the allowable temperature, through switching to an avoidance shift mode.

An in-vehicle control device includes: a requested torque calculation unit which calculates a requested torque on the basis of a driving state of a vehicle; a requested torque change amount calculation unit which calculates the amount of change in requested torque per unit time as a requested torque change amount; an estimated generation torque calculation unit which calculates estimated generation torque estimated as being generated by an engine; an estimated generation torque change amount calculation unit which calculates the amount of change in estimated generation torque per unit time as an estimated generation torque change amount; and an abnormality detection unit which detects an abnormality of the engine on the basis of the integrated value of a difference between the requested torque change amount and the estimated generation torque change amount, and outputs abnormality determination for the engine.

A method for operating an internal combustion engine comprises providing a vehicle having an internal combustion gasoline engine including multiple cylinders and wherein the engine is operating in a deactivated cylinder mode, receiving a torque request if a cylinder reactivation torque smoothing mode is active, setting a variable torque ratio to 1.0 if the torque request is greater than a fast exit threshold torque, setting the variable torque ratio to 0.0 if the torque request is less than a slow exit threshold torque, setting the variable torque ratio to a value between 0.0 and 1.0 if the torque request is between the fast exit threshold torque and slow exit threshold torque, and calculating a component of final engine output torque.

A vehicle includes an engine and at least one controller. In response to a change in a rate of change of a driver control input to the vehicle, the at least one controller is programmed to alter conditions under which the engine will be started and stopped such that engine-on time increases due to the rate increasing and decreases due to the rate decreasing.

A method of cruise control for a vehicle includes: checking for cruise conditions, determining whether the vehicle is in cruisecontrol mode, and if so, controlling the cruising speed of the vehicle until an exit signal is detected; checking the throttle deviation, to determine throttle stability; checking cruising speed, whereby if conditions for throttle stability are met, the speed deviation of the vehicle is calculated, and the cruising speed is set; if conditions for cruising have been met, issuing a cruising prompt message to the driver, and detecting actions of the driver, and if it is thereafter detected that the driver has released the throttle pedal, then entering the vehicle into cruise control mode whereby the vehicle speed is automatically controlled to the set cruising speed. A system is provided to perform the method. A cruise control which is low-cost, requires no control buttons, and offers a simple product structure is achieved.
