    摘要： An engine control system comprises a torque request module, an immediate torque control module, an actuation module, and an expected torque control module. The torque request module generates an expected torque request and an immediate torque request. The immediate torque control module controls a spark advance of an engine based on the immediate torque request. The actuation module selectively reduces the expected torque request based on the immediate torque request and a spark capacity. The spark capacity is based on a difference between a first engine torque and a second engine torque, determined at a current airflow. The first engine torque is determined at a first spark advance and the second engine torque is determined at a second spark advance that is less than the first spark advance. The expected torque control module that controls a throttle valve area based on the expected torque request.

    摘要： An improved control for the heater element of a motor vehicle engine exhaust gas oxygen sensor determines the temperature of the heater element and adjusts the heater element current by closed-loop control to minimize deviation of the heater element temperature from a desired heater temperature determined in relation to the desired oxygen sensor temperature. The heater temperature is calculated based on the heater element resistance, and the heater resistance is adaptively adjusted to account for sensor-to-sensor variation. The adaptive adjustment is updated based on a deviation of the measured heater element resistance from an expected value under predetermined calibration conditions at engine start-up.

    摘要： A minimum torque module selectively determines a first minimum propulsion torque based on second and third minimum propulsion torques when a torque converter clutch is in unlocked and locked states, respectively. A zero pedal torque module selectively sets a zero pedal torque equal to the first minimum propulsion torque. A pedal request module determines a pedal torque request based on an accelerator pedal position, a vehicle speed, and the zero pedal torque. A driver request module determines a driver axle torque request based on the pedal torque request. A shaping module selectively shapes the driver axle torque request into a shaped driver axle torque request. A conversion module converts the first minimum propulsion torque into a minimum axle torque. A final driver request module sets a final driver axle torque request equal to a greater of the shaped driver axle torque request and the minimum axle torque.
