PROBLEM TO BE SOLVED: To more properly support driving according to a driver. SOLUTION: A driving environment determination part 11 selects driving environment determination cluster distribution based on distribution selection information (identification information ID, weather information W, time zone information TB), and when defining specified manipulated variables Hsb based on a vehicle speed V, steering manipulated variables S and brake manipulated variables B as a parameter for determination, estimates a driving environment by collating the parameter for determination with the selected environment determination cluster distribution. A target value setting part 15 sets target values OD and OT of an inter-vehicle distance and the time to collision suitable for the current driving environment or a driver, weather, and time zone by using an estimation model prepared for each driving environment. A driving situation estimation part 16 outputs the degree of deviation of actual detection values D and TTC corresponding to the target values OD and OT as an estimation value showing the driving situations of the driver.
