This arrangement makes it possible to properly control a motion of an actual vehicle to a desired motion while properly considering the characteristics of a road surface reaction force acting from a road surface on a wheel.

Vehicle Control Device

An engine and an electronic control unit perform cooling capacity increase control for compensating for a insufficiency of the cooling capacity of a cooling device. The electronic control unit performs a variety of control for a vehicle, including control of the cooling device. At that time, the electronic control unit calculates the target value of the cooling capacity of the cooling device, calculates the estimate value of the cooling capacity that will be able to be exerted in the future under the current control, compares the target value and the estimate value, and when it is determined from the result of the comparison that the cooling capacity will be insufficient, performs the cooling capacity increase control. The electronic control unit changes the contents of the cooling capacity increase control according to the degree of insufficiency of the estimate value with respect to the target value.

PROBLEM TO BE SOLVED: To provide a tire air pressure monitoring device of a vehicle for notifying tire air pressure by notification sound to facilitate an air filling work. SOLUTION: A monitoring device body 9 is constituted of an air pressure determining part 92 for performing an air pressure determination based on a detection result inputted from an input interface 91, an output command signal generating part 93 for generating an output command signal based on the determination result of the air pressure determining part 92, and an output interface 94 connected with a speaker 53, etc. When tire air pressure starts to rise, the output command signal generating part 93 recognizing a change of tire air pressure outputs a notification sound output signal to the speaker 53 via the output interface 94 after generating a notification sound output signal for only the tire. As a result, the notification sound starts to be produced from the speaker 53 when a worker starts the air filling work, for instance. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a parking assisting system and a parking assisting device, capable of certainly assisting parking or putting into a garage with a simple structure. SOLUTION: At a specified position of a vehicle center line in an entrance passage of each parking space, a beacon (a tenth beacon 10a, a eleventh beacon 11a,...,) having a function sending/receiving radio waves is installed. When a vehicle 1, for example, is going to park to a twelfth parking space 12 while moving backward, a pneumatics sensor unit 4 mounted on the vehicle detects a radio wave signal sent from a twelfth beacon 12a covered by the vehicle. And an EPS that is a steering means of the vehicle 1 starts steering wheel operation control at a position detecting the radio wave signal of the twelfth beacon 12a. Therefore, the vehicle 1 moves backward while rotating by a standard minimum rotation radius about an installing position of the twelfth beacon 12a, so that the vehicle 1 can be easily parked to the twelfth parking space 12.
