A vehicle includes a traction battery and a controller programmed to operate the traction battery according to an estimated value of a battery state of health parameter. The estimated value is updated based on drive cycle parameters of the vehicle over a time interval. The state of health parameters include a battery capacity and a resistance of the traction battery.

A vehicle includes: at least one rotary electric machine; an inverter that drives the rotary electric machine; a capacitor connected between a paired electric power lines that is connected to the inverter; and a control unit. When a vehicle collision is detected, the control unit executes first control for discharging electric charges stored in the capacitor by performing a switching operation of the inverter so as to prevent a flow of a q-axis current but cause a flow of a d-axis current to the rotary electric machine. The control unit stops the first control in a specified case and executes second control for performing the switching operation of the inverter so as to reduce the current flowing through the rotary electric machine to be lower than that during execution of the first control. The control unit executes third control for shutting down the inverter after execution of the second control.

An air control system with an integrated diagnostic device for a motor vehicle includes: a carrier structure, an air output opening, a closing element arrangement with one or several closing elements adjustably placed on the carrier structure, a power unit which is constructed to adjust the closing element arrangement in an adjustment movement, a diagnostic device to acquire information about the condition of the closing element arrangement, an interface to convey data at least from the diagnostic device to another device, wherein for at least one closing element of the closing element arrangement the air control system also includes a resistance element associated with said closing element which is constructed to temporarily change the torque or force required in a predetermined phase of the adjustment movement for the adjustment of the closing element arrangement, wherein the diagnostic device acquires at least one operating parameter of the power unit as information about the status of the closing element arrangement.

A single-piece, lightweight, energy-absorbing, and impact resistant battery tray for a battery enclosure for a vehicle includes a lower floor including an impact resisting structure, upwardly sloping side walls integrally formed with the lower floor, and a peripheral flange integrally formed with the upwardly sloping side walls and including an energy absorbing structure.

The present disclosure in some embodiments provides a vehicle braking apparatus including wheel brakes for providing a braking force to one or more front and rear wheels, a first actuator including a first hydraulic circuit supplying braking force to at least some of wheel brakes, a first master cylinder adjusting hydraulic pressure of the first hydraulic circuit, and a first motor, a second actuator including a second hydraulic circuit supplying a braking force to at least a remainder of the wheel brakes, a second master cylinder adjusting hydraulic pressure of the second hydraulic circuit, and a second motor, an EPB generating a braking force on rear wheels, a regenerative braking system generating a regenerative braking force, and an ECU for controlling at least one of the first actuator, second actuator, electronic parking brake, or regenerative braking system upon determining whether the first actuator and the second actuator malfunction.

A combined power take off and controller includes a power take off including a housing that is adapted to be supported on a housing of a source of rotational energy, an input mechanism that extends through an opening provided in the housing and is adapted to be rotatably driven by the source of rotational energy whenever the source of rotational energy is operated, and an output mechanism that is rotatably driven by the input mechanism and that is adapted to be connected to a rotatably driven accessory. The controller is responsive to one or more operating conditions of the power take off for monitoring and/or controlling the operation thereof.

A method for reinforcing safety of a vehicle on a ramp applied to a vehicle is performed by a first priority anti-skid countermeasure control in which a brake is operated together with displaying an occurrence of the skid of a vehicle/vehicle stop message on a ramp by a controller when the vehicle starts, a second priority anti-skid countermeasure control in which compensating an idle torque is performed together with displaying a guidance of anti-skid function operation/vehicle stop message is performed, a third priority anti-skid countermeasure control in which displaying a turn-off/vehicle stop message is performed, and a fourth priority anti-skid countermeasure control in which forcibly shifting to a N (neutral) stage or permitting the shift together with displaying a forcibly switching to the shift stage N stage/vehicle stop message is performed.

A fuel tank system for a vehicle includes a fuel tank, a fuel supply passage, a canister, an evaporated fuel gas supply passage, a communication passage, a backflow prevention device, first and second pressure measurement devices, and a control device. The fuel tank stores fuel supplied by the fuel supply passage. The canister adsorbs evaporated fuel gas generated in the fuel tank and supplied through the evaporated fuel gas supply passage. The backflow prevention device is provided in a pipe line of the fuel supply passage, and prevents a backflow of the fuel from the fuel tank. The first and second pressure measurement devices respectively measure pressures in the fuel supply passage and the evaporated fuel gas supply passage. The control device diagnoses the communication passage as being blocked when a difference between pressure values measured by the first and second pressure measurement devices exceeds a predetermined value.

An all-wheel-drive vehicle includes a primary drive axle, a secondary drive axle, and an all-wheel-drive powertrain configured to selectively power the primary and secondary axles. The powertrain includes a powerplant and a clutch that couples the powerplant to the secondary axle when engaged and that decouples the powerplant from the secondary axle when disengaged. A controller is programmed to disengage the clutch to disable all-wheel drive and propel the vehicle solely with the primary drive axle based on repeated occurrence of power output of the powertrain being less than a value.

A method for reinforcing safety of a vehicle on a ramp applied to a vehicle is performed by a first priority anti-skid countermeasure control in which a brake is operated together with displaying an occurrence of the skid of a vehicle/vehicle stop message on a ramp by a controller when the vehicle starts, a second priority anti-skid countermeasure control in which compensating an idle torque is performed together with displaying a guidance of anti-skid function operation/vehicle stop message is performed, a third priority anti-skid countermeasure control in which displaying a turn-off/vehicle stop message is performed, and a fourth priority anti-skid countermeasure control in which forcibly shifting to a N (neutral) stage or permitting the shift together with displaying a forcibly switching to the shift stage N stage/vehicle stop message is performed.
