A vehicle includes an electric motor and an engine selectively coupled to the electric motor. The vehicle has an electric motor controller configured to, in response to (i) an absence of receiving a motor command signal within a predetermined time, (ii) a battery voltage being below a first threshold and (iii) a motor speed exceeding a second threshold, restrict operation of the electric motor to a limited operating mode and control the electric motor to generate a charging torque for a battery.

Methods and systems of an electrical vehicle are provided that recognize a power system fault with the vehicle and in response autonomously drive the vehicle to an identified safe location to self-destruct. Upon reaching the location, the vehicle can evaluate the location using imaging sensors to determine whether the location is free of objects, animals, or people. If not, the vehicle may autonomously drive to another safe location. Prior to destruction, the vehicle sends messages, including information about the power system fault, to at least one device or third party. The messages include location information for the vehicle or information about the power system fault.

A vehicle includes a fault-tolerant braking system that controls a brake assembly which is configured to adjust a braking force applied to one or more wheels. The fault-tolerant braking system further includes a brake-by-wire (BBW) system and a vehicle control module (VCM). The BBW system is configured to control the brake assembly in response to a braking request. The VCM is configured to detect a fault of at least one of the brake assembly and the BBW system. In response to detecting the fault, the VCM selectively operates the vehicle between a normal operating mode and at least one degraded driving mode that limits operation of at least one of the vehicle engine and the vehicle transmission compared to the normal operating mode.

An engine room temperature rise restricting apparatus including an open and close detector of the grille shutter, and a controller including a CPU and a memory coupled to the CPU, wherein the CPU and the memory are configured to perform: detecting a stuck-closed failure of a grille shutter of a condition that the grille shutter remains closed regardless of an open instruction for the grille shutter, based on signal from the open and close detector; and controlling a speed ratio of a continuously variable transmission so that an upper limit of an engine rotational speed or an engine driving force when the stuck-closed failure is detected is smaller than an upper limit of the engine rotational speed or the engine driving force when the stuck-closed failure is not detected.

A transfer for a four-wheel drive vehicle includes a case, an input shaft, a output shaft, a output member, a friction clutch, an actuator, a pressing mechanism, a locking sleeve, a first locking sleeve driving mechanism, and a second locking sleeve driving mechanism. The second locking sleeve driving mechanism is configured to move a locking sleeve independently of the actuator and the first locking sleeve driving mechanism. The second locking sleeve driving mechanism includes a pushpin. The pushpin is configured to move in a second axial direction that is perpendicular to a first axial direction and engage with a cam groove. The pushpin is configured to move the locking sleeve toward the output member side as the locking sleeve rotates when the pushpin is engaged with the cam groove.

A vehicle includes a battery control module and a controller. The battery control module may be configured to issue at regular intervals a message indicative of an SOC of a battery. The controller may be configured to, in an absence of receiving the messages at the regular intervals while in a key-on state and a torque demand is present, restrict power flow between the battery and an electric powertrain to a limit that is based on a predicted SOC to provide limited propulsive force.

The invention relates to a shutter-controlling device for a motor vehicle, comprising at least one shutter (4, 8) and an actuator (2) that moves said at least one shutter (4, 8) between a closed position and an open position. The device is characterised in that said shutter (4, 8) can be detached from said actuator (2) in the event of failure of said actuator (2). The invention also relates to a frame (3) comprising such a device.

A vehicular active air flap assembly capable of being opened or closed during a failure may include an air flap that can be manually opened to allow air required during the operation of the vehicle to be supplied into the engine compartment even when the air flap malfunctions, wherein the vehicular active air flap assembly is configured to operate the air flap mounted on a hole formed in a radiator grill to allow cooling air to be supplied into an engine compartment of a vehicle or block the supply of cooling air and wherein the air flap is rotatably coupled at opposite end portions thereof to the radiator grill, and at least one end portion thereof is mounted to be movable in a front-rear direction of the vehicle.

A vehicle includes an engine, a first MG (motor generator), a second MG, a planetary gear mechanism provided among the engine, the first MG and the second MG, a battery, and an ECU. The ECU executes batteryless travel control when the battery is abnormal. The batteryless travel control includes engine F/B control for controlling a rotation speed of the engine to become a target rotation speed, and power balance control for controlling a requested driving force to be output and allowing a power generated by the first MG to become equal to a power discharged by the second MG. When the rotation speed of the engine is higher than a threshold speed higher by a prescribed value than the target rotation speed while the batteryless travel control is in execution, the ECU decreases the requested driving force.

The invention relates to a flap control device for a motor vehicle comprising at least one flap (4, 8) and an actuator (2) moving said at least one flap (4, 8) between a closed and open position. The device is characterized in that said flap (4, 8) is able to be detached from said actuator (2) in the event of failure of said actuator (2). The invention also relates to a frame (3) comprising a device as defined hereinabove.
