Driving-assistance control apparatus

A driving-assistance control apparatus comprising:

• a memory storing instructions;
• and
• at least one hardware processor configured to implement:
• a straight-running determinator that determines whether or not a vehicle is running straight;
• a head-position detector that detects a head position of a driver;
• a driving-posture determinator that determines a posture of the driver, based on the head position detected by the head-position detector;
• and
• a driving-assistance processor that performs acceleration preparation control for raising a reaction speed for acceleration operation or deceleration preparation control for raising a reaction speed for deceleration operation in accordance with an output of the driving-posture determinator, when the straight-running determinator determines that the vehicle is running straight, wherein at least one of:
• when based on an output of the driving-posture determinator, determining that the posture of the driver is a forward-inclined posture, the driving-assistance processor performs the acceleration preparation control, and
• when based on an output of the driving-posture determinator, determining that the posture of the driver is a backward-inclined posture, the driving-assistance processor performs the deceleration preparation control.
