摘要： PROBLEM TO BE SOLVED: To accurately determine the state of a road surface on which a vehicle travels. SOLUTION: In this device for determining the state of a road surface, the relationship between wheel deceleration and vehicle body acceleration among a high-μ road, an intermediate-μ road, and a low-μ road is related to the state of a road surface and stored in memory 18M. From the relationship, vehicle body acceleration detected by a vehicle body acceleration detecting circuit 12, and wheel deceleration speed obtained by differentiating wheel speed (detected by a wheel speed detecting circuit 14) in which extremely little noise is included, a road surface determining circuit 18 determines a road surface on which a vehicle travels.

摘要： PROBLEM TO BE SOLVED: To estimate a road surface μ with high accuracy in a condition close to a limit. SOLUTION: An ABS controller 34 superimposes impulse-like hydraulic excitation on the current wheel pressure in the direction in which hydraulic pressure rises. Using a road surface μ gradient estimating device 18, a road surface μgradient in a condition closer to a limit than the current braking condition is estimated from vehicle body velocity v0 and wheel angular velocity ωobtained from a wheel velocity signal detected by a wheel velocity sensor 10 and the excitation component (u) of brake torque obtained from a pressure sensor 24. A road surface μ estimating device 40 estimates a road surface μ on the basis of the estimated road surface μ gradient and brake torque in a reference condition obtained from a signal detected by the pressure sensor 36.

摘要： PROBLEM TO BE SOLVED: To provide a cooling control device protecting an electric pump when cooling water is poured in. SOLUTION: ECU 100 executes delivery quantity control process to control delivery quantity of cooling water of an electric water pump (W/P) 310 of a cooling device 300. When intention of pouring water is designated by operating a water pouring button 400 or the like, the ECU 100 improves water pouring characteristic by setting a target value of pump rotation speed Rp regulating delivery quantity to a target pump rotation speed RpA generally higher than a target pump rotation speed RpB following a fuel saving mode when water is not poured in. On the other hand, the ECU 100 executes air inclusion detection process in parallel with delivery quantity control process. In air inclusion detection process, the ECU 100 determines air inclusion when rotation speed deviation ΔRp which is difference between the pump rotation speed Rp and the target pump rotation speed RpA is larger than a threshold ΔRpth. When air inclusion occurs, the ECU 100 intermittently operates the electric W/P 310. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To more properly judge idle running of the electric pump for circulating a cooling medium used for a cooling device of an internal combustion engine without using an electric motor current, and appropriately respond when it is judged that an electric pump has been running idle.
SOLUTION: In a cooling device of an internal combustion engine, when duty ratio dB is not less than a threshold value dBref and a revolution speed Np of the electric pump 30 is not less than a threshold value Nref and besides when a revolution speed difference calculated by subtracting an estimated revolution speed Nest from the revolution speed Np of the electric pump 30 is not less than a threshold value ΔNref, the idle running of the electric pump 30 is determined (S130 to S150). When the idle running determined continued and a given idle running time period has elapsed, the electric pump 30 is suspended for a given stop time period (S160, S190 to S210). As a result, without detecting the current passing through a coil of the electric pump 30, the idle running of the electric pump 30 can be more properly judged, preventing overheating and damage in the electric pump 30.

摘要： PROBLEM TO BE SOLVED: To provide an engine cooling device properly preventing overheat of an engine, by performing a control in view of a distance between two vehicles.
SOLUTION: The engine cooling device is suitably used for cooling the engine, by circulating cooling water. Concretely, the engine cooling device acquires a distance between one's own vehicle and the vehicle ahead, and performs a control increasing a radiation amount of a radiator when the distance between the two vehicles is not more than a predetermined distance. In this case, the engine cooling device performs at least any one of a control with respect to an electric water pump, a control operating an electric fan, a control adjusting the distance between two vehicles, and a control providing information to a driver. Therefore, the overheat of the engine caused by decrease in travelling air to be supplied to the radiator, is prevented.

摘要： PURPOSE:To realize sky hook control in a vehicle unequipped with a car level sensor in particular by operating the variable speed of a relative distance in an interval between a suspension and a car body, etc., on the basis of at least one acceleration detected value, and calculating the desired value in response to the variable speed of the relative distance and a vertical displacement speed. CONSTITUTION:A car body is supported by four sets of suspensions 1FL, to 1RF supported by respective wheels of front FL, front FR, rear RL and rear RR, and each of them is provided with a shock absorber capable of adjusting each damping force. In addition, an area of an orifice is adjusted according to a tuning angle in each output of four actuators 3FL to 3RR connected to these elements, whereby each damping force is varied. An electronic control unit ECU calculates a target damping force coefficient in sky hook control at each wheel on the basis of plural numbers of accelerating signals Sg, and when each damping force coefficient of these shock absorbers at that time is varied, four driving signals DFL to DRR are outputted to these shock absorbers 3FL to 3RR.
