A method for monitoring a drive-by-wire system of a motor vehicle, including: temporally offset reading in of at least two input values of an input quantity of an operating element of the motor vehicle; ascertaining a change over time or rate of change over time of the input quantity from the at least two read-in input values; determination of a monitored quantity for the motor vehicle operation from the change over time or rate of change over time; selection of a monitoring function on the basis of the monitored quantity; monitoring of the monitored quantity for the ascertained motor vehicle operation by the monitoring function.

A driving assistance apparatus is configured to perform an assistance control of assisting in driving a vehicle, when a first condition and a second condition are satisfied, in a situation in which a target is recognized. The driving assistance apparatus is provided with: a determinator configured to determine a state of the assistance control. The determinator is configured (i) to determine that the state of the assistance control is a standby state if a standby condition is satisfied, wherein the standby condition requires that the first condition is satisfied, but the second condition is not satisfied, in the situation in which the target is recognized, and (ii) to determine that the state of the assistance control is an interruption state if an interruption condition is satisfied, wherein the interruption condition requires that the first condition is no longer satisfied while the satisfaction of the standby condition is continued.

Systems and methods are provided for simulating rev-matching in hybrid electric vehicles (HEVs). In particular, increased engine response is provided while downshifting during acceleration. The transmission of an HEV may include an electronic control unit that controls the speed of the engine to simulate gears, and increases the speed of the engine responsive to a driver using the gear selector to shift from one of the simulated gears to a lower one of the simulated gears, thereby providing the desired rev-matching experience. The increased engine response can be reflected in a target engine speed that is calculated based on specific gear ratios associated with each of the simulated gears.

A driving force control system for a hybrid vehicle for reducing a required time to launch the hybrid vehicle after selecting a reverse range while maintaining a driving force. The control system is configured to change an engine start threshold to restrict a startup of the engine upon satisfaction of a restricting condition, in which a low mode is established by a transmission mechanism, and a reverse drive range is selected.

A battery discharge limit control system is provided. The system includes a motor driven by receiving the power stored in a battery and a clutch connected to the rotary shaft of the motor. Additionally, an engine includes the rotary shaft connected to the rotary shaft of the motor through the clutch and a transmission changes the rotational speed of the rotary shaft of the motor or the engine based on the input of the shift stage instruction to output the rotational speed to a driving wheel of a vehicle. A controller opens the clutch and drives the motor in the reverse rotation, when the input of the shift stage instruction is a reverse shift stage.

A regenerative braking control system of an AWD (all-wheel-drive) hybrid vehicle including a front wheel HEV (hybrid electric vehicle) powertrain and a rear wheel EV (electric vehicle) powertrain is provided. The control system includes a manipulating instrument mounted to a steering wheel for manual shifting and regenerative braking control by a driver's manipulation, and a controller for adjusting a regenerative braking amount and controlling a shift pattern of each of a front wheel motor of the front wheel HEV powertrain and a rear wheel motor of the rear wheel EV powertrain by receiving a (−) or (+) manipulation signal or a hold manipulation signal of the manipulating instrument.

Systems and methods to control the vehicle speed of a vehicle includes a motor and a controller coupled to the motor. The controller is structured to: determine that a speed of a vehicle is at or above a predetermined speed limit; activate a motor speed governor responsive to an input received by the controller, wherein the motor speed governor is structured to control a vehicle speed; and adjust an output torque based on the vehicle speed being at or above the predetermined speed limit.

A regenerative braking control system and a regenerative braking control method using a paddle shift of a hybrid vehicle, include a paddle switch including a first paddle shift for a down shift and a second paddle shift for an up shift, a first controller electrically connected to the paddle switch and configured to determine a deceleration control amount of regenerative braking for stopping the vehicle as a hold operation of the first paddle shift is input, and a second controller electrically connected to the first controller and configured to control a motor torque for the regenerative braking according to the deceleration control amount determined from the first controller and to control hydraulic braking of the vehicle to be executed when reaching a stop state of the vehicle.

In a hybrid vehicle, when a required driving force is equal to or smaller than a first upper limit driving force, a control device sets a target driving force to the required driving force. When the required driving force is larger than the first upper limit driving force, the control device sets a target compensation power of a power storage device, based on a difference between the required driving force and the first upper limit driving force. The control device sets a second upper limit driving force of a driveshaft when an upper limit power is output from an engine and the power storage device is charged or discharged with a power based on the target compensation power. The control device sets a target driving force to the smaller between the required driving force and the second upper limit driving force. This configuration suppresses deterioration of the driver's drive feeling.

Provided are a shift position sensor detecting a shift position of a vehicle; a yaw rate sensor detecting a yaw rate of the vehicle; a turning angle calculation unit calculating, based on the yaw rate between a start time and an end time of a first time, a turning angle of the vehicle in a plan view between the start time and the end time; and a determination unit determining that the vehicle executes a specific retreat operation when the determination unit determines, based on a detection value of the shift position sensor, that the shift position is switched to an advance position, a reverse position, and the advance position within the first time, and a maximum cumulative value of the turning angle of the vehicle in one direction between the start time and the end time, calculated by the turning angle calculation unit, is a threshold value or more.
