PURPOSE:To improve reliability of stored data in the past history of a system in a rear wheel steering controller which employs two microprocessors. CONSTITUTION:A rear wheel steering controller is provided with a first microprocessor 1 which computes a target rear wheel steering amount in accordance with the situation of a vehicle, a second microprocessor 2 which performs the same computation as the first microprocessor to obtain a target rear wheel steering amount, and a comparison section 6 which compares the respective target rear wheel steering amount which is computed by the first and second microprocessors, outputs the past history when the results of comparison coincide, does not output the past history when they do no coincide, and becomes an inhibition means. |
