Title:
CONTROL DEVICE AND VEHICLE CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2023140882
Kind Code:
A
Abstract:
To provide a control device and a vehicle control system which highly accurately correct a temperature characteristic error of an acceleration sensor and calculate an inclination angle with improved accuracy.SOLUTION: A control device comprises: an acquisition section which is installed in the control device and acquires a sensing result of an acceleration sensor detecting acceleration of a vehicle; a calculation section which calculates an inclination angle on the basis of the sensing result; an estimation section which estimates a temperature around the acceleration sensor; an identification sensor which identifies a temperature characteristic error at the temperature on the basis of the estimated temperature around the acceleration sensor and temperature characteristic error information indicating a correspondence relation between the temperature around the acceleration sensor and the temperature characteristic error of individual acceleration sensor; a correction section which calculates a corrected inclination angle with an error of the inclination angle corrected on the basis of the identified temperature characteristic error; and an output section which outputs the corrected inclination angle to another device.SELECTED DRAWING: Figure 3
