An electronic control unit permits a shift operation to a neutral position, by which a manual transmission 14 is switched to neutral, during coasting control. Accordingly, shifting to the neutral position can be performed only by the shift operation. Thus, power transmission can be blocked after termination of the coasting control. In addition, the electronic control unit prohibits the shift operation to a particular gear after the transmission is switched to neutral. Thus, overreving or underreving at the termination of the coasting control can be suppressed.

Even when a motor fails in an EV travel mode in which a clutch is disengaged, an amount of hydraulic oil that is supplied to the clutch can be secured by reducing a transmission leaked amount. Accordingly, the clutch can be engaged, and an oil pump can be driven by power of an engine. Thus, an evacuation travel by the engine is allowed when the motor fails in the EV travel mode.

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 driving force control apparatus for controlling a driving force to be transmitted to a wheel includes a processor. The processor is configured to set, when the wheel is idled, a control amount of the driving force to be transmitted to the wheel based on a vehicle acceleration.

A method for controlling a line pressure of a hybrid vehicle includes applying, by a controller, a set current corresponding to a target pressure to a first solenoid valve controlling the line pressure, driving, by the controller, a second solenoid valve to open an engine clutch after the applying step, comparing, by the controller, a difference value between a real pressure of the engine clutch sensed by a pressure sensor and the target pressure with a preset pressure after the driving step, and as a result of performing the comparing step, if the difference value is equal to or greater than the preset pressure, controlling, by the controller, an increase of a revolution per minute (RPM) speed of the electric oil pump and an increase of a pressure of the first solenoid valve to be alternately generated.

A control apparatus for a hybrid electric vehicle includes: an engine control portion for controlling an operation state of an engine; and a driving-mode control portion for controlling the vehicle so as to realize selected driving mode or modes. The driving modes include a main-drive-wheel driving mode in which a drive power is distributed to main drive wheels, and an all-wheel driving mode in which the drive power is distributed to the main and auxiliary drive wheels. When the all-wheel driving mode is selected in the main-drive-wheel driving mode with the engine being in a stopped state, the engine control portion is configured to maintain the stopped state of the engine until completion of switching from the main-drive-wheel driving mode to the all-wheel driving mode, and to start the engine after a predetermined operation is executed by the driver of the vehicle to drive the vehicle.

An apparatus includes a torque circuit and a clutch circuit. The torque circuit is structured to monitor a torque demand level of an engine. The clutch circuit is structured to (i) disengage an engine clutch of a transmission to decouple the engine from the transmission in response to the torque demand level of the engine falling below a threshold torque level and (ii) disengage a motor-generator clutch of the transmission to decouple a motor-generator from the engine in response to the torque demand level of the engine falling below the threshold torque level. The motor-generator is directly coupled to the transmission.

Techniques are disclosed for performing hybrid simulation operations with an autonomous vehicle. A method of testing autonomous vehicle operations includes receiving, by a computer, a pre-configured scenario that includes one or more simulation parameters and one or more initial condition parameters, sending, to the autonomous vehicle and based on the one or more initial condition parameters, control signals that instruct the autonomous vehicle to operate at an operative condition, and in response to determining that the autonomous vehicle is operating at the operative condition, performing a simulation with the one or more simulated objects and the autonomous vehicle to test a response of the autonomous vehicle.

A method for operating a hybrid vehicle having a prime mover including an internal combustion engine and an electric machine, the vehicle further having a transmission connected between the prime mover and a driven end and including multiple shift elements, the vehicle further having a separating clutch connected between the internal combustion engine and the electric machine, and a starting component which is provided by a separate launch clutch or by a shift element of the transmission. The method includes monitoring a rotational speed of one of the internal combustion engine, the electric machine, the transmission, or the driven end during travel with the internal combustion engine running and the separating clutch engaged. The method further includes determining an increase in driving resistance, and decoupling the internal combustion engine when the monitored rotational speed falls below or reaches a first limiting value by disengaging the separating clutch.

A hybrid electric vehicle includes an engine including a cylinder and a spark plug, a motor, a clutch provided between the engine and the motor, and a control device configured to start combustion in the engine by supplying electric power to the spark plug while cranking the engine via the clutch using the motor when a start request for the engine is issued. The control device includes a measuring unit configured to measure a power supply time of the spark plug in cranking of the engine, a count unit configured to count a long-time power supply number which is the number of times the power supply time is equal to or greater than a predetermined first time, and a correction unit configured to correct a cranking torque necessary for cranking the engine and required for the motor such that the cranking torque increases as the long-time power supply number increases.
