摘要： A braking control system for a motor vehicle in which various braking controls, including an antiskid braking control and a traction control, are realized comprehensively, accurately and smoothly without being based on the slip factor of a wheel. The actual wheel speed (Wvr) of the rear wheel side is detected, and the desired wheel speed (Wrf) of the front wheel side is set so as to be lower than the actual wheel speed (Wvr). Besides, the actual wheel speed (Wvf) of the front wheel side is detected, and the deviation (ef) between the actual wheel speed (Wvf) and the desired wheel speed (Wrf) is detected. Subsequently, the desired braking torque (Nrf) of the front wheel side is calculated from the deviation (ef) and the actual wheel speed (Wvf). Further, the desired braking torque (Nrr) of the rear wheel side is set on the basis of the desired braking torque (Nrf). The braking pressure of the braking apparatus is controlled so as to establish the desired braking torques (Nrf) and (Nrr).

摘要： Disclosed is an internal combustion engine control device that is capable of accurately estimating a turbine flow rate during a transient operation of an internal combustion engine with a turbocharger having a WGV. Steps are performed to acquire an exhaust gas flow rate mcyl (=mB), a WGV opening WG (=X), and a turbine rotation speed Ntb (=Na) during the transient operation of the internal combustion engine. Steps are then performed to calculate the turbine flow rate (=mtA) and exhaust gas flow rate mcyl (=mA), which prevail when the turbine rotation speed Ntb and WGV opening WG acquired during the transient operation are achieved during a steady operation. Next, a step is performed to calculate the turbine flow rate (=mtB) during the transient operation by applying the flow rate ratio of mtA to mA to the exhaust gas flow rate mcyl during the transient operation. Preferably, the turbine rotation speed Ntb during an Ntb transient operation is estimated by using a turbine flow rate change amount Δmt (=mtB−mtA) during the transient operation.

摘要： A control system of an internal combustion engine changing an operating timing of a valve in an internal combustion engine where a valve drive cam (13) and a pump drive cam (150) are both provided on a valve camshaft (1) is provided. That control system has a device inhibiting the operating timing from being returned in a direction reverse to the direction of the target operating timing during change of the operating timing. Further, in the control system, the relative rotational phases of the valve drive cam and the pump drive cam are set considering utilization of the composite reaction torque of the valve operation drive reaction torque and the fuel pump drive reaction torque acting on the valve camshaft for changing the operating timing in the direction of the target operating timing.
