Abstract

A vehicle controller configured to accurately determine a driver's intention to intervene in steering is provided. An ECU (40) includes a deviation calculating circuit (41), an assist control circuit (60), an automatic steering control circuit (70) including an intervention determination switching circuit (72), an adder (42), a current command value calculating circuit (43), and a motor control signal calculating circuit (44). The intervention determination switching circuit (72) includes a count amount calculating circuit (82), an adder (83), an immediately-preceding count amount output circuit (85), a switching determination circuit (86), and an output switching circuit (87). The count amount calculating circuit (82) calculates a count amount (C) having a positive value or a negative value based on a steering torque absolute value (|Th|) calculated by an absolute value switching circuit (81). The adder (83) calculates a total count amount (Ca) that is the total sum of a presently calculated count amount (C) and an immediately-preceding count amount (Co) calculated in an immediately-preceding calculation cycle. The switching determination circuit (86) determines a driver's intention to intervene in steering, based on whether the total count amount (Ca) is equal to or greater than a count amount threshold value (Tc).
