A method for controlling the actuation of an actuatable restraint to help protect a vehicle occupant in response to a rollover event is implemented in a controller of a vehicle safety system that includes the actuatable restraint. To implement the method, the controller is configured to execute a roll discrimination metric that discriminates the occurrence of a ramp rollover event or an embankment rollover event in response to a vehicle roll rate (R_RATE) having a magnitude that exceeds a predetermined threshold roll rate (R_RATE). The controller is also configured to execute a switching metric that is operative to reduce the predetermined threshold roll rate (R_RATE) in response to a vehicle pitch rate (P_RATE) having a magnitude that exceeds a predetermined threshold pitch rate (P_RATE).

A method for classifying an accident event of a two-wheeled vehicle, in particular a bicycle. The method can be run in the form of an algorithm in a device comprising an analysis unit in order to indicate to the rider or a third party that the two-wheeled vehicle has been involved in a collision or has fallen over using a corresponding generated and/or transmitted item of information. The device can be used in a two-wheeled vehicle, such as a bicycle or in particular in an electric bicycle. However, it can of course also be used in a motorcycle or another single-track vehicle.

A physical quantity detection circuit includes: a detection signal generation circuit generating a detection signal, based on an output signal from a physical quantity detection element; an analog/digital converter circuit converting the detection signal into a first digital signal and converting a test signal into a second digital signal; a test signal generation circuit generating the test signal; and a malfunction diagnosis circuit diagnosing a malfunction of the analog/digital converter circuit, based on the second digital signal. A full-scale voltage of the analog/digital converter circuit is selected from among a plurality of voltages having different magnitudes, according to a power supply voltage. The test signal includes an upper limit value test signal, a lower limit value test signal, and a first intermediate value test signal. The test signal generation circuit performs resistive voltage division of the full-scale voltage and thus generates the first intermediate value test signal.

A method and a system for impact detection in a stationary vehicle are provided. The method includes putting a telematics device into a sleep mode and performing a first micro wakeup. In response to determining that a first value read from a sensor during the micro wakeup is greater than a noise threshold, increasing a frequency of the micro wakeups and a sampling rate of the sensor. The method also includes reading a second value from the sensor during a second wakeup, performing a regular wakeup, and sending the first and second values during the regular wakeup.
