The present invention includes a method of regulating the tension of the belt member, in which case the engine torque which can be anticipated can be evaluated sufficiently accurately and the tension is best distributed. Therefore, a signal for accurately evaluating the engine torque is given by the engine control mechanism that controls the internal combustion engine.

In the second configuration, the signal is an amount of air mass sucked by the internal combustion engine or a signal derived therefrom and an ignition advance angle of the internal combustion engine. The clean evaluation of the engine torque can reduce the tension of the belt member, thereby improving the efficiency of the transmission.

FIELD: engine building. SUBSTANCE: invention relates to internal combustion engines. In the method of controlling a power plant of a motor vehicle during an acceleration event, it is identified that the torque demand will give a high level of NOx emissions from the engine, and in response to this electric machine is used so that requirement of torque is satisfied by combination of electric machine and engine.

Method and apparatus for estimating applied wheel torque in a motor vehicle

A vehicle traction control system is controlled in part by a signal value indicative of estimated wheel torque. The estimated wheel torque value is produced within the vehicle's electronic engine control (EEC) module by summing a first value which indicated the estimated torque attributable to engine combustion and a second value which is proportional to engine acceleration/deceleration which indicates the amount of torque attributable to the inertial movement of engine and drive train masses. The second value is modified by a third value based on the speed ratio across the transmission. Before summing the two signal components, the signal which indicates combustion torque is preferably delayed with respect to the signal indicating inertial torque by a delay interval whose duration varies with engine speed to take into account the delay between intake fuel rate changes and combustion forces as well as delays attributable to the timing of the calculations themselves.

Method for controlling a vehicle drive unit

The invention relates to a method for controlling a vehicle drive unit which comprises at least two individual motors. The total actual torque (14) is continuously compared (15) to a permitted total torque (10), whereby the total actual torque (14) is calculated from individual actual torque values (11, 12) of the at least two individual motors and the permitted total torque (10) is calculated from permitted individual torque values (7, 8) of the at least two individual motors. An error reaction is triggered if the comparison (15) demonstrates that the total actual torque (14) is greater than the permitted total torque (10).

Controller and control method for vehicle

A controller is configured to control a vehicle that includes an internal combustion engine and an automatic transmission. The controller is configured to execute a shifting process that switches a gear ratio of the automatic transmission and a lean operation process that operates the internal combustion engine with an air-fuel ratio of the air-fuel mixture in a cylinder leaner than a stoichiometric air-fuel ratio. The controller is further configured to, when executing the shifting process during execution of the lean operation process, set an air-fuel ratio in a case in which the shifting process is being executed to a value closer to the stoichiometric air-fuel ratio than an air-fuel ratio in a case in which the shifting process is not being executed.

Vehicle control method and vehicle control device

A vehicle includes an internal combustion engine, an exhaust purification catalyst, and an air fuel ratio sensor. The internal combustion engine is structured to be motored by an electric motor generator. The exhaust purification catalyst is structured to purify exhaust gas of the internal combustion engine. The air fuel ratio sensor is located upstream of the exhaust purification catalyst and structured to sense an air fuel ratio. When a quantity of oxygen stored in the exhaust purification catalyst is larger than a reference value, it is determined that inflow of oxygen into the exhaust purification catalyst has an insignificant effect on exhaust performance. Then, fuel injection of the internal combustion engine is stopped, the internal combustion engine is motored, and air fuel ratio learning is performed for learning of a sensed value of the air fuel ratio sensor.
