A rollover predictor judgment device for a combination vehicle includes a lateral acceleration sensor, a yaw rate sensor, an articulate angle sensor, and a judgment device in a form of a retarder controller. The judgment device judges that the combination vehicle is in a rollover predictor status when a first lateral acceleration calculated based on a detection value of the lateral acceleration sensor is a first threshold or more or when a second lateral acceleration calculated based on a detection value of the yaw rate sensor and a detection value of the articulate angle sensor is a second threshold or more.

A rollover predictor judgment device (30) for a combination vehicle (1) includes a lateral acceleration sensor (26), a yaw rate sensor (27), an articulate angle sensor (23), and a judgment device in a form of a retarder controller (32). The judgment device judges that the combination vehicle is in a rollover predictor status when a first lateral acceleration calculated based on a detection value of the lateral acceleration sensor (26) is a first threshold or more or when a second lateral acceleration calculated based on a detection value of the yaw rate sensor (27) and a detection value of the articulate angle sensor (23) is a second threshold or more.

The present invention describes a system comprised of sensors, microcontrollers, wireless communication modules, and methods for utilizing said sensor system to determine, in real-time, a threat and/or theft of a catalytic converter. An alarm signal is then generated by connecting with the security system of a premises, if available, and relevant parties and law enforcement are notified of the threat and/or theft event.

A lateral rollover risk warning device can report vehicle rollover risk in real time during traveling with no need for inputting radius of a curved path in advance.

It includes a first acceleration sensor detecting an external force applied in up-down direction of a vehicle body; an angular velocity sensor detecting a rotation around vehicle axis of vehicle body; and a second acceleration sensor detecting an external force in right-left direction of vehicle body, with an arithmetic part using detection results given by first acceleration sensor and angular velocity sensor to calculate a limit index of vehicle being led to a rollover, and using detection result given by second acceleration sensor to calculate a comparative index to be compared with limit index in real time; and a reporting part using limit index and comparative index to report lateral rollover risk warning information telling the rollover risk.

The present invention provides an autonomous emergency braking system of a vehicle including a sensor module which radiates a signal when the vehicle is being driven to the front of the vehicle to detect an object in front of the vehicle, an autonomous control module which determines whether the object collides with the vehicle and when it is determined that the object collides with the vehicle, puts the brake on the vehicle, and a sensor control module that when the vehicle puts on the brakes and is forwardly inclined, adjusts a signal radiating direction of the sensor module to control the sensor module to detect the object.

Methods and apparatus to determine a vehicle pitch angle for luminous range control are disclosed. An example method to determine a pitch angle of a vehicle relative to a surface on which the vehicle stands for luminous range control of a headlight of the vehicle includes determining, at a standstill of the vehicle, a change of a load pitch angle of the vehicle based on output from a gravitation sensor, determining, as the vehicle is driven, an average value of the pitch angle of the vehicle and an average value of a dynamic pitch angle of the vehicle, the average value of the dynamic pitch angle determined via output from an acceleration sensor, determining a current value of the dynamic pitch angle via the output from the acceleration sensor, determining a current value of the load pitch angle of the vehicle based on the average value of the pitch angle and the average value of the dynamic pitch angle, determining, based on the current value of the load pitch angle and the current value of the dynamic pitch angle, the pitch angle of the vehicle relative to the surface, and controlling an orientation of the headlight of the vehicle based on the pitch angle of the vehicle relative to the surface.

A tilt detection device for a moving object includes the first acquisition portion that acquires first tilt information detected by a first tilt sensor disposed in a sensor package housing mounted in the moving object and a peripheral monitoring sensor. The second acquisition portion acquires second tilt information detected by a second tilt sensor disposed in a portion of the moving object other than the sensor package housing. The first difference identification portion identifies a first difference between a tilt of the moving object relative to a common reference state and a tilt of the sensor package housing relative to the common reference state based on the first tilt information and the second tilt information. The tilt detection portion determines that the sensor package housing is tilted from an initial position when the first difference does not fall within a first allowable range.
