A driving assist device includes a camera and a controller. The camera detects the presence of another vehicle ahead of a host vehicle. The controller sets a detection field of the camera. The controller determines that another vehicle has cut in front of the host vehicle if a degree to which the other vehicle has entered into the detection field exceeds or equals a first prescribed value when the host vehicle is traveling, or the other vehicle has cut in front of the host vehicle if the degree exceeds or equals a second prescribed value that is smaller than the first prescribed value when the host vehicle is stopped.

A braking force control apparatus for a saddle ride vehicle includes a transmission controller which reduces driving force of an engine by a predetermined speed reduction ratio and transmits the driving force to a drive wheel, a clutch device which connects—disconnects the driving force between the engine and the transmission, a brake device which generates braking force on the drive wheel, and a sensor which detects a state of the transmission. The transmission switches between a neutral state and an in-gear state, and when the sensor detects that the transmission is switching from the neutral state to the in-gear state, the controller causes the brake device to generate braking force on the drive wheel, and then releases the braking force upon completion of the switching to the in-gear state.

A control device according to the present invention performs an automatic stop control in which an injection of fuel from a fuel injection valve is stopped and a rotation of an engine is stopped when an automatic stop condition is satisfied. Furthermore, the control device controls an injection operation of fuel and an ignition operation to the fuel in consideration of compression when the fuel is actually ignited in an expansion stroke cylinder, when a re-start demand occurs after an initiation of the automatic stop control and the engine is to be re-started by an ignition start-up. Specifically, the control device predicts a crank angle at an actual ignition time point in a case where processing for performing the ignition start-up at the present time whenever a predetermined time period has passed. Then, the control device initiates the ignition start-up when the crank angle falls within a predetermined range in which a sufficient compression can be attained. Thereby, the engine is more certainly re-started by the ignition start-up.

The present invention makes it possible to appropriately grasp a stop cause when a vehicle stops. An ECU 5, which controls a vehicle including wheels and a vehicle body connected to the wheels includes: a wheel stop detection unit 138 that detects a stop of the wheels; a vehicle body stop detection unit 133 that detects a stop of the vehicle body; and a stop cause determination unit 141 that determines a stop cause of the vehicle based on a stop timing of the wheels detected by the wheel stop detection unit 138 and a stop timing of the vehicle body detected by the vehicle body stop detection unit 133. The stop cause determination unit 141 may determine that the stop cause is contact of the vehicle body with an obstacle when the stop timing of the vehicle body is earlier than the stop timing of the wheels.

A method for controlling restart of a vehicle is provided. The method includes allowing the vehicle to enter into an ISG state and allowing the vehicle to actuate the Auto Hold. Whether the vehicle fulfills a condition for releasing the Auto Hold is then determined and operation of the Auto Hold is released in response to determining that the vehicle fulfills the condition for releasing the Auto Hold. Additionally, the method includes determining whether the vehicle fulfills a condition for releasing the ISG and releasing the ISG and restarting an engine in response to determining that the vehicle fulfills the condition for releasing the ISG.

A motor vehicle automatic engaged stop system includes an automatic transmission driving at least one wheel and has at least one brake member preventing wheel rotation when engaged and allowing wheel rotation when disengaged. A controller communicates with each of: the brake member to control the brake member; the automatic transmission to control a condition of the automatic transmission, and with a signal device. A brake pedal in communication with the brake member engages the brake member when depressed by a vehicle operator. After the motor vehicle reaches a zero speed the controller energizes the signal device to notify the vehicle operator to release the brake pedal and maintains a vehicle stopped condition with the brake pedal in a released condition and when the motor vehicle is positioned anywhere between uphill and downhill orientation planes.

Provided is a control device for a vehicle including a continuously variable transmission. The control device includes a lock-up clutch, an oil pump, an electric motor, and a device control unit. The lock-up clutch is disposed in a torque converter coupled to the engine and switchable between an engaged state and a released state. The oil pump is driven by the engine and supplies a hydraulic oil to the continuously variable transmission. The electric motor is coupled to the engine and controlled to be in a powering state in which the engine is rotationally driven. The device control unit controls the lock-up clutch to put into the released state and controls the electric motor to put into the powering state if a discharge pressure of the oil pump falls below a threshold value at the time of a vehicle deceleration in which a fuel supply to the engine is cut off.

A driving assistance method includes the steps of, by a controller, acquiring state information of a driver during travelling of autonomous driving and issuing a warning to the driver when the controller determines that the driver is not facing forward based on the state information of the driver. In the driving assistance method, a warning is prohibited when the driver is facing a lane change direction during the travelling of autonomous driving.

A vehicle control apparatus, which controls an execution of an autonomous driving of a vehicle, is configured to: acquire a driving characteristic information item indicating a numerical value or a degree of a driving characteristic used in an autonomous driving of the vehicle; and set the driving characteristic to be used in the autonomous driving of the vehicle with the acquired driving characteristic information item. The driving characteristic to be used in the autonomous driving is set using the acquired driving characteristic information item to be different from a driving characteristic of a manual driving operation performed by a user of the vehicle.

A vehicle determines whether or not a passage permit condition of the vehicle according to an instruction content of a traffic light in front of the vehicle is satisfied. If it is determined that the passage permit condition is not satisfied, the vehicle temporally stops in front of the traffic light and transmits an assist requiring signal to a remote facility. A display device of the remote facility displays reference image information indicating shot image information of the vehicle that temporally stops in front of the traffic light. An operator of the remote facility inputs positional information of pixels that make up the traffic light contained in the reference image information. The remote facility transmits assist information including the positional information to the vehicle. Based on the positional information, the vehicle determines again whether or not the passage permit condition is satisfied.
