A power adjustment system and a power adjustment method of an autonomous mobile device are provided. In the power adjustment method, two first current control signals respectively transmitted to two drivers are outputted by a control module. A tilt angle of the autonomous mobile device is detected by an inertial measurement module. A travel route is planned by a navigation module, and the control module obtains a steering angle of the autonomous mobile device during a traveling process. According to different weight values of the autonomous mobile device stored in a database module, a weight of the autonomous mobile device is estimated by the control module. According to the two first current control signals and the weight, the steering angle, and the tilt angle of the autonomous mobile device, two second current control signals respectively transmitted to the two drivers are outputted by the control module.

A tip-over prevention system for dumping vehicles includes a tilt detector operably coupled to one of a cargo body and a chassis of a dumping vehicle. At least a portion of the cargo body is configured to be raised by a piston, and the tilt detector is configured to detect a current tilt. The system includes a fluid release valve placed in fluid communication with the piston which is activated in response to the tilt detector detecting a current tilt that exceeds a preset tilt limit. Activation of the fluid release valve releases a pressure in the piston causing the cargo body of the vehicle to lower.

A falling-over detection device is mounted on a motorcycle. The falling-over detection device includes an acceleration sensor that detects acceleration at an interval decided by an interval adjusting device, a threshold value determining device that determines whether or not a detected angle is larger than a predetermined threshold value, a counting device that counts the number of times it is determined that the detected angle is larger than the threshold value, and a falling-over determining device that determines that the motorcycle has fallen over in a case where the count is successive a predetermined number of times. The interval adjusting device uses a pulse generated based on white noise as an interval, and therefore noise does not successively affect a value detected by the acceleration sensor.

A device for controlling a pressure of an oil pump in a vehicle is provided to. The device includes a sensor that detects an inclination of a vehicle and an oil pump that pumps oil in an oil pan to pressure transfer the oil to an engine of the vehicle. A controller determines an inclination value of the vehicle based on the information from the sensor and adjusts the operating mode of the oil pump to adjust the pressure of the oil supplied to the engine.

A vehicle rollover simulator is provided. The rollover simulator includes a cage assembly that is rotationally suspended in a frame assembly. A transmission motor assembly is removably connected to the frame assembly and to the cage assembly to rotate the cage assembly to an inverted position for training. A brake assembly is provided that prevents rotation of the cage assembly and significantly enhances stability. The assemblies of the simulator can be disassembled and are sized to be readily carried by hand through typically dimensioned doorways, hallways and stairwells such that manually moving the rollover simulator is readily accomplished.

An apparatus for determining a rollover condition of a vehicle may include: a rate sensing unit configured to sense one or more rates of a pitch rate PitchRate and a yaw rate YawRate of a vehicle and a roll rate RollRate_IN; an acceleration sensing unit configured to sense horizontal acceleration and vertical acceleration of the vehicle; a conversion unit configured to convert the horizontal acceleration and vertical acceleration into a pitch rate PitchRate_ACC and a yaw rate YawRate_ACC; a combination unit configured to calculate a pitch rate PitchRate_IN and a yaw rate YawRate_IN by combining the one or more rates with the pitch rate PitchRate_ACC and the yaw rate YawRate_ACC; and a determination unit configured to calculate a roll angle RollAngle, and determine whether the vehicle has rolled over, based on the roll rate RollRate_IN and the roll angle RollAngle.

A vehicle steering intervention system and method prevents a loss of vehicle control condition or a vehicle rollover condition. The system includes a driver input torque sensor for sensing torque applied by a driver to a steering wheel, a steering angle sensor for sensing a steering angle, and a speed determination device for determining a vehicle speed. An electronic power steering unit includes an electronic processor and a memory. The electronic power steering unit determines a vehicle steering intervention threshold based on the torque sensed, the steering angle, and the vehicle speed. The electronic power steering unit predicts whether the vehicle steering intervention threshold will be exceeded within a predetermined time based on a torque gradient and/or a steering angle gradient. When the vehicle steering intervention threshold is predicted to be exceeded, the electronic power steering unit reduces a power steering assist and/or provides a counter steer force.

A parking system for a personal mobility includes at least one parking stand configured to be mounted on the personal mobility and to automatically unfold or fold, a boarding sensor configured to be mounted on the personal mobility and to detect whether the personal mobility is boarded or deboarded, and a controller configured to determine whether the personal mobility is boarded or deboarded based on the detection of the boarding sensor and to control operation of the parking stand so that the parking stand unfolds when the personal mobility is deboarded and the parking stand folds when the personal mobility is boarded.
