Systems and methods for controlling engine brake disengagement in a vehicle include a controller receiving a signal indicative of a command to disengage an engine brake while the vehicle engine is in engine brake engaged condition. The engine can be subjected to a first negative torque under the engine brake engaged condition. The controller can cause the engine brake to be gradually disengaged over a time period using a predefined torque ramp rate, responsive to the signal. The gradual disengagement of the engine brake can be in the form of a phased out disengagement, and can reduce vehicle engine jerk associated with engine brake disengagement.

A driver's hands on/off detection system for detecting whether a driver's hands are on/off a steering wheel during driving is applied to a vehicle. When a driving assistance system is operated by a controller during driving, the driver's hands on/off detection system calculates an electronic motor driven power steering system (MDPS) torque representative value and a vehicle measurement data representative value as a representative value ratio between sensors, and divides a disturbance driving area and a normal driving area by a magnitude of the representative value ratio between sensors to perform sensor detection correction control of a hands on/off check using a disturbance torque threshold to the torque filtering value or torque-based sensing control of a hands on/off check using an upper/lower torque limit value to the torque filtering value, thereby reducing the hands on/off detection errors during driving with only a vehicle-mounted sensor without using a capacitive sensor.

In a control device (100) for a vehicle which is equipped with an automatic transmission (TM) and capable of automated driving control, when an increase in a required driving force is predicted during the execution of the automated driving control, a vehicle speed of the vehicle is maintained or decelerated until an increase timing of the required driving force, an engine rotation number is increased within a standby period until the increase timing of the required driving force, a torque of the engine is decreased in response to the increase in the engine rotation number, and a shift gear level of the automatic transmission is shifted downward.

Longitudinal acceleration, intended travel angle, wheel speed, and requested drive torque signals are measured for a vehicle. The longitudinal acceleration, intended travel angle, wheel speed, and requested drive torque signals are then evaluated. A brake torque is calculated as a function of a propulsive torque, wherein the propulsive torque is produced by a power source for the vehicle. The brake torque is applied when the longitudinal acceleration signal exceeds a longitudinal acceleration threshold, the intended travel angle signal is between intended travel angle limits, the wheel speed signal is less than a minimum speed threshold, the requested drive torque signal exceeds a requested drive torque threshold, and a torque threshold is exceeded.
