PROBLEM TO BE SOLVED: To suppress variation of reaction force not intended by a driver in a reaction force control of a vehicle operation instrument. SOLUTION: The driving operation auxiliary device for a vehicle has traveling state recognition means 10, 20 for detecting the vehicle condition and a traveling environment around the vehicle; a risk potential calculation means 30 for calculating risk potential around the own vehicle based on a signal from the traveling condition recognition means 10, 20; a reaction force calculation means 30 for calculating operation reaction force generated in the vehicle operation instrument based on the risk potential calculated by the risk potential calculation means 30; an operation reaction force generation means 60 for generating the operation reaction force in the vehicle operation instrument based on a signal from the reaction force calculation means 30; and a reaction force variation speed calculation means 30 for calculating the variation speed of the operation reaction force calculated by the reaction force calculation means 30. The device further has a characteristic change means 30 for changing the variation characteristic of the operation reaction force calculated based on the risk potential when the reaction force variation speed calculated by the reaction force variation speed calculation means 30 is faster or slower than a predetermined speed.
