Document Type and Number:
WIPO Patent Application WO/2020/095651
Kind Code:
A1
Abstract:
In order to detect an anomaly in a vehicle even at an extremely slow vehicle speed between vehicle stoppage to lock-up, a TCU (22) for controlling a vehicle (1) and being provided with an engine (2) for generating a drive force, a transmission (4) for gear-shifting the output rotation of the engine, a front-back G-sensor (27) and a right-left G-sensor (28) for measuring a vehicle acceleration, and an output rotation sensor (26) for detecting the rotational speed of an output shaft (8) of the transmission, is configured to detect an anomaly in the vehicle by comparing a measurement value of the vehicle acceleration measured by the acceleration sensors with a calculated value of the vehicle acceleration calculated from an output signal of the output rotation sensor.
