Disclosed is a control apparatus for a stopped state holding apparatus which can be switched between a holding state for holding a vehicle in a stopped state and a cancelled state in which the holding state is cancelled. The control apparatus includes a detection section for detecting a manipulation state of an operation section manipulated by an operator to switch the stopped state holding apparatus to the holding state or the cancelled state, and a control section for controlling operation of the stopped state holding apparatus on the basis of the detected manipulation state. In the case where the detection section detects a particular manipulation state in which a manipulation of the operation section for switching the stopped state holding apparatus continues for a predetermined period of time or longer, the control section controls the operation of the stopped state holding apparatus irrespective of the particular manipulation state.

A device for controlling fail-safe for a vehicle includes a driving device that engages a clutch and a brake individually in a stopped state of the vehicle when a shift by wire system fails, and a controller that locks the engaged clutch and brake, and unlocks the clutch and the brake when a predetermined unlock manipulation pattern is input using a brake pedal and an accelerator pedal of the vehicle.

A vehicle system includes a first vehicle platform including a first computer configured to operate by means of electric power from a first electric power source and perform traveling control of a vehicle, a second vehicle platform including a second computer configured to operate by means of electric power from a second electric power source different from the first electric power source and perform traveling control of the vehicle, and an autonomous driving platform including a third computer configured to perform autonomous driving control of the vehicle by transmitting a control instruction including data for autonomously driving the vehicle to the first computer when the first vehicle platform is in a normal state and perform autonomous stoppage control of the vehicle by transmitting a control instruction including data for causing the vehicle to autonomously stop to the second computer when the first vehicle platform is in an abnormal state.

A method, apparatus and vehicle for controlling a ride level for a vehicle having at least one first axle having a first air suspension and/or one second axle having a second air suspension, a parking brake and an operating brake, including: reading a ride level variation signal, indicating a ride level variation to be performed; providing a parking break release signal to an interface to a parking brake valve that, responding to the ride level variation signal, releases and engages the parking brake installation, the parking brake release signal being for actuating the parking brake valve for releasing the parking brake installation; and providing a first control signal to an interface to a first valve of the first air suspension and/or a second control signal to an interface to a second valve of the second air suspension while using the ride level variation signal for performing the ride level variation.

Systems and methods for operating an engine and a transmission to reduce a catalyst light off time are disclosed. In one example, clutches of a transmission are operated to provide a desired load to the engine so that engine combustion stability may be improved while supplying heat to a catalyst so that the catalyst light off time may be reduced.

Controls for improved performance of a vehicle equipped with start-stop control logic are disclosed. Deviation from nominal engine start-stop control logic for the internal combustion engine occurs when a predetermined mission related type of stop event will occur or is occurring that is different from other stop event types that are controlled by the nominal engine start-stop control logic. At least one of a location and a payload associated with the mission related stop event type is provided as an input to the controller before the vehicle arrives at the stop event so that operating parameters of the vehicle are controlled accordingly.

Systems and methods for controlling a park pawl system of a hybrid vehicle having a hybrid powertrain comprising an engine and a hybrid transmission comprising at least one electric propulsion motor, the systems and methods each utilizing a control system configured to detect, using a main control system portion, a desired park state based on at least an input via a transmission gear selector and an input via a brake pedal and detect, using a distinct monitoring system portion, whether the desired park state is valid based on at least the transmission gear selector and brake pedal inputs. When the desired park state is valid, the control system commands the park pawl system to the desired park state. When the desired park state is invalid, however, the control system commands an electric park brake of the vehicle to prevent movement at a driveline of the vehicle.

A parking lock device includes a parking mechanism, a lock state switching member, a selector, a gradient detector, a switching controller, and an engine speed controller. The lock state switching member locks a parking gear when supply of hydraulic pressure is stopped. When hydraulic pressure is supplied, the lock state switching member releases the lock of the parking gear. The selector receives operation to select a shift range. The gradient detector detects a gradient of a road surface. When a parking range is selected, the switching controller stops supplying the hydraulic pressure to the lock state switching member. When another shift range is selected, the switching controller supplies the hydraulic pressure to the lock state switching member. When the parking range is selected and the gradient of the road surface is equal to or larger than a predetermined value, the engine speed controller increases an engine speed.

In a vehicle control system (1, 101, 201) configured for autonomous driving, a control unit executes a stop process by which the vehicle is parked in a prescribed stop area when it is detected that the control unit or a driver has become incapable of properly maintaining a traveling state of the vehicle, and a stop maintaining process for keeping the vehicle parked following the vehicle coming to a stop in the stop process. The control unit keeps the brake lamp turned on while the stop maintaining process is being executed.

Provided is a hydraulic pressure control device. A hydraulic pressure control device includes a solenoid valve configured to supply hydraulic pressure to switch between an engaged state and a released state of a lock-up clutch, and a transmission control device configured to control the solenoid valve. The solenoid valve supplies hydraulic pressure to switch between a parking locked state and a parking released state of a parking lock mechanism, in addition to switching of the lock-up clutch.
