摘要： PROBLEM TO BE SOLVED: To improve running feeling without carrying out gear change for shift down while a vehicle is turning a corner by setting an upper limit gear change step and calculating horizontal turning acceleration to process a speed at the upper limit gear change step. SOLUTION: An automatic transmission controller 12 detects a car speed by a gear change processing means, and a car speed sensor 44 detects a car speed. A recommended gear change step determining means 101 determines a recommended gear change step of an automatic transmission which corresponds to a car speed and a road situation, and an upper limit gear change step determining means 103 sets an upper limit gear change step based on the recommended gear change step. A horizontal turning acceleration calculation means 105 calculates horizontal turning acceleration, and a gear change restricting means 106 restricts gear change. The automatic transmission controller 12 performs gear change processing at the upper limit gear change step. Consequently, gear change is restricted when horizontal turning acceleration exceeds a reference value. Accordingly, gear change for shift down is not done while a vehicle is turning a corner so that running feeling can be improved.

摘要： PROBLEM TO BE SOLVED: To improve travelling feeling in the case when corners continue. SOLUTION: It has a car speed sensor 44 to detect car speed, a recommended speed change step deciding means 101 to decide a recommended shift step of an automatic transmission in correspondence with car speed and a road status, an upper limit shift step setting means 103 to set an upper limit shift step in accordance with the recommended shift step and a shift treatment means to carry shift treatment at the upper limit shift step. Additionally, the recommended shift step deciding means 101 is furnished with a restraint means 106 to restrain the number of decision of the recommended shift step on corners. In this case, as the number of decision of the recommended shift step is restrained at the corners, the number of decision of the recommended shift step decreases, and it is possible to prevent frequent change of the shift step. Consequently, it is possible to improve travelling feeling.

摘要： PROBLEM TO BE SOLVED: To optimize operation of an on-vehicle device according to the characteristic of the facility. SOLUTION: This vehicular control device controls on-vehicle equipment of various types on vehicle so that, when it is recognized to be within a facility, it may operate according to the facility by an in/out facility judging means 116 of the navigation ECU 100. For example, when it is recognized to be in a parking lot, an engine ECU 120 blocks acceleration by controlling a throttle actuator 124 and a fuel injection device 126. Thus useless acceleration is limited in the parking lot and overrun and the like can be prevented.

摘要： PURPOSE:To provide a controller of a car friction type clutch that is able to do a judder judgment without suspending once the slip control as well as without installing a speed sensor anew for judder detection. CONSTITUTION:With a judder judging means 154, the occurrence of judder vibration in a lockup clutch 40 corresponding to a friction type clutch is judged on the basis of a difference between both rotational variations of rear wheels 22L, 22R and front wheels 30L, 30R during slip control. In addition, when the occurrence of this judder vibration in the lockup clutch 40 is judged, the slip control of the lockup clutch 40 is altered by a slip control altering means 156. Since the rotational variation by the judder vibration in the lockup clutch 40 is damped by a chain drive 24, the rotational variation due to unevenness on a road surface is exclusively produced in these front wheels 30L and 30R, so that the judder vibration in the lockup clutch 40 is judged on the basis of a difference in the rotational variation of the rear wheels 22L and 22R.

摘要： PURPOSE:To reduce loss of power by carrying out control for reducing line pressure based on centrifugal hydraulic pressure which acts on its hydraulic reacting means accompanying rotation of the hydraulic reacting means so as to reduce driving torque of a hydraulic pump in the state that torque capacity in a friction engaging means is secured necessarily and sufficiently. CONSTITUTION:As a line pressure Pl is changed according to electric current applied on an electromagnetic proportional valve, and thus, an electric current Ip put out at Step 7 is an electric current value for setting the line pressure smaller by the amount of pressure which is P acquired at Step 3 or Step 6, a throttle pressure to be applied on a throttle pressure port 29 is reduced at a pressure control valve 15 and a force press a spool 16 upward is reduced accordingly. As a result, a line pressure which appears on a line hydraulic pressure oil passage 31 is reduced.

摘要： PURPOSE:To ensure sufficient power performance for a vehicle in high weight and to avoid an unreasonable speed change for the vehicle in low weight by providing a main transmission part, subtransmission part, vehicle weight detecting means and a means switching the subtransmission part to a low speed side when the vehicle increases its weight to a predetermined value or more. CONSTITUTION:An automatic transmission is constituted of a main transmission part enabling a speed change shift to be switched to two or more speeds and a subtransmission part arranged in series on a power transmitting system to this main transmission part and enabled to be switched to at least high and low speed sides. Then detecting vehicle weight for whether or not it is in a predetermined value or more, the subtransmission part is switched to the low speed side when the vehicle weight is in the predetermined value or more. As the result, the transmission is used with gear ratio in a speed change shift, attained by the main transmission part, decreased (or being left as is) for the high vehicle weight and with the subtransmission part in a high speed side for the low vehicle weight.
