A drive assist system includes an occupant monitoring apparatus, a determination apparatus, and a drive assist control apparatus. The occupant monitoring apparatus monitors a physical state of an occupant, including a driver, of a vehicle. The determination apparatus determines a traveling state and a stopped state of the vehicle. The drive assist control apparatus executes a control to secure safe traveling upon determining that sleep duration of the occupant is less than a predetermined time and quality of sleep thereof is lower than a predetermined level on the basis of monitoring information acquired by the occupant monitoring apparatus. The drive assist control apparatus includes one or more processors that perform, in a case where determination information from the determination apparatus indicates the stopped state, a control of appropriately restricting the driver's driving operation on the basis of at least the sleep duration and the quality of sleep of the driver.

A control system for a hybrid vehicle that reduces delay in engagement of a clutch when shifting an operating mode by manipulating the clutch. A controller is configured to adjust a speed of a first motor to a first standby speed at which the speed difference in a first clutch is reduced when an operating mode will be shifted from a single-motor mode to a first mode, and adjust a speed of the first motor to a second standby speed at which a speed difference in the second clutch is reduced when the operating mode will be shifted from the single-motor mode to a second mode.

A drive force control system controls acceleration of a vehicle accurately in line with an operation of an accelerator pedal to improve an acceleration feel. A controller calculates a corrected target acceleration when a required acceleration is large and an operating speed of the accelerator pedal is fast, and converts the corrected target acceleration into a target driving force to propel the vehicle so as to achieve the corrected target acceleration by generating the target driving force.

A vehicle includes a drive device for traveling, and a control device configured to control the drive device so that the vehicle travels with a target driving force based on an accelerator operation amount. The control device is configured to set the target driving force such that a change in the target driving force with respect to a change in the accelerator operation amount is gentler in a case where steady traveling is desired as compared with a case where the steady traveling is not desired. Therefore, in a case where the steady traveling is desired, a variation of a vehicle speed with respect to a slight variation of the accelerator operation amount can be gentle and continuous steady traveling can be facilitated.

An electrified vehicle may include an electric motor coupled to a battery to propel and brake the vehicle, a pedal generating a pedal position signal including a released position signal, friction brakes configured to provide a stopping force to vehicle wheels, and a controller programmed to control the motor and the brakes in response to the pedal being released to decelerate the vehicle to a stop, and to control the motor and an engine (in hybrid vehicles) to inhibit propulsive torque to the wheels after stopping due to the pedal released position until receiving driver input indicative of a request for moving the vehicle, such as depressing the brake or accelerator pedal, or activating an automated vehicle maneuver, such as a parking maneuver, cruise control, or stop-and-go control. Inhibiting torque may include inhibiting creep torque and/or operating the electric machine to charge the battery when the engine is running.

A vehicle control system configured to control deceleration of a vehicle properly according to a driver's intention in one-pedal mode. In the one-pedal mode, a controller controls deceleration of the vehicle based on a deceleration level set in accordance with a speed of the vehicle. If the brake pedal is manipulated to decelerate the vehicle while the vehicle is operated in the one-pedal mode and an operating amount of an accelerator pedal falls within the decelerating range, the controller updates the deceleration level based on an operation of the brake pedal.

A controller as a control apparatus for a hybrid vehicle determines whether or not to perform switching from a first traveling mode in which a hybrid vehicle is caused to travel using torque of a motor without using torque of an engine to a second traveling mode in which the hybrid vehicle is caused to travel using at least the torque of the engine. The controller, when determining that switching is to be performed from the first traveling mode to the second traveling mode, performs control to reduce output torque of the motor by a predetermined amount. After this control, the controller shifts a first clutch from a released state to an engaged state so that the torque of the motor is transmitted to the engine via the first clutch, and cranks the engine using the motor to start the engine.

An action to be performed by a vehicle in response to conflicting input signals can be determined. A sensor signal and an accelerator pedal signal can be received. The sensor signal can indicate a possible need to reduce a speed of the vehicle. The accelerator pedal signal can indicate that an accelerator pedal has been set to a position to increase the speed. An existence of first and second conditions can be determined. The first condition can be that a receipt of the accelerator pedal signal occurred concurrently with a receipt of the sensor signal. The second condition can be that a manner in which the accelerator pedal was set to the position is a better match to a brake pedal usage profile than to an accelerator pedal usage profile. In response to the existence of the first and the second conditions, a brake can be caused to be actuated.

A vehicle speed control device is configured to: acquire an AP opening rate of an accelerator pedal of a vehicle; perform deceleration control according to an AP opening rate-target driving force characteristic; when an operation element is operated for deceleration in a state where pressing on the accelerator pedal has been released, change the characteristic to a second characteristic representing, for a deceleration force to be applied due to the release of pressing on the accelerator pedal, a second deceleration force larger than a first deceleration force that is based on the before-change characteristic; and terminate the deceleration control according to the second characteristic when a target driving force that is based on a result of applying the AP opening rate to the second characteristic has reached a target driving force that is to be applied at the release of pressing on the accelerator pedal according to the before-change characteristic.

A control system has at least one electronic control unit for controlling an internal combustion engine in a hybrid vehicle, which records at least the vehicle speed and the driver's desired driving performance and the driving performance specified by a safety control system or a driver assistance system. The control unit is designed such that, below a pre-defined vehicle speed threshold and/or in the event of recognition of an urban area, while in a purely electric driving mode, it only engages the internal combustion engine when the current desired driving performance exceeds a pre-defined upper threshold, preferably once the maximum tractive force at the wheel for purely electric driving is at least reached.
