The present application generally relates noise and vibration mitigation in a vehicle. More specifically, the application teaches a system and method for applying a noise and vibration constraint to a vehicle subsystem, measuring a sound level within the vehicle cabin, determining the sound level exceeds a threshold level making the noise constraint redundant and removing the noise constraint in response to the sound level exceeding the threshold level.

A hybrid vehicle in which an electric storage device can be cooled during propulsion in an electric vehicle mode. In the hybrid vehicle, the battery supplies electricity to a drive motor when the hybrid vehicle is powered by the drive motor in an electric vehicle mode while stopping the engine. The battery is cooled by an intake air flowing through an intake passage of the engine. A detector detects a temperature of the battery, and a controller operates a motor-generator when the temperature of the battery exceeds a first threshold value during propulsion in the electric vehicle mode.

A push cart includes a wheel, a motor, an obstacle detector, and a controller. The motor is configured to generate a rotational force that rotates the wheel. The obstacle detector is configured to detect an obstacle. The controller is configured to execute, in response to detection of the obstacle by the obstacle detector, avoidance control to control driving of the motor such that a movement of the push cart is limited. The controller is configured to disable execution of the avoidance control in response to a determination that a specified disabling condition is satisfied.

Methods and systems are provided for adjusting clutch pressures and electric machine torques as a function of a stability metric threshold(s) in order to balance performance and charging of an onboard energy storage device. In one example, a method includes during an upshift of a transmission from a first gear to a second gear, adjusting a clutch pressure of the transmission to adjust slippage of a clutch in response to a vehicle stability control parameter exceeding a threshold. In this way, torque delivered to a transmission output shaft may be reduced, which may increase vehicle stability.

A computing system can determine a vehicle action based on determining a free space map based on combining video sensor data and radar sensor data. The computing system can further determine a path polynomial based on combining the free space map and lidar sensor data. The computing system can then operate a vehicle based on the path polynomial.

A mode switching method of a hybrid vehicle includes: determining a reference on-power as a reference for switching from a first mode to a second mode and a reference off-power as a reference for switching from the second mode to the first mode; determining a minimum on-power, a minimum off-power, and a maximum off-power; and determining a final on-power and a final off-power using the reference on-power, the reference off-power, the minimum on-power, the minimum off-power, and the maximum off-power.

A vehicle control apparatus includes an engine, a refrigerant compressor, a lock up clutch, a throttle valve, and first, second, and third deceleration controllers. The second deceleration controller controls the lock up clutch to a slip state and controls the throttle valve openwise on the condition that the refrigerant compressor is in the stopped state on decelerated travel of a vehicle in a second speed region in which a vehicle speed is lower than a first vehicle speed and higher than a second vehicle speed lower than the first vehicle speed. The second deceleration controller controls the lock up clutch to a disengaged state and controls the throttle valve closewise on the condition that the refrigerant compressor is in the operative state on the decelerated travel of the vehicle in the second speed region.
