Vehicle deceleration controller

A vehicle deceleration controller comprising:

• accelerator condition detecting means for detecting a vehicle accelerator condition;
• vehicle speed detecting means for detecting a vehicle speed;
• road surface gradient detecting means for detecting a gradient of a driving road surface;
• vehicle weight detecting means for detecting a total vehicle weight including a load of the vehicle;
• braking force generating means for generating a braking force for braking the vehicle;
• judging means for judging release of the vehicle accelerator based on a detected signal of the accelerator condition detecting means;
• required deceleration memory means for memorizing a required deceleration that varies in accordance with the vehicle speed and the gradient of the driving road surface;
• required deceleration determining means for determining the required deceleration using the required deceleration memorized in the required deceleration memory means and the vehicle speed detected by the vehicle speed detecting means and the gradient of the driving road surface detected by the road surface gradient detecting means;
• operation mode memory means for memorizing vehicle deceleration that varies in accordance with an operation mode of the braking force generating means, the vehicle speed and the total vehicle weight;
• operation mode determining means for determining a required operation mode referring to the operation mode memorized in the operation mode memory means and based on the required deceleration determined by the deceleration determining means, the vehicle speed detected by the vehicle speed detecting means and the total vehicle weight detected by the vehicle weight detecting means;
• and
• outputting means for operating the braking force generating means with the required operation mode when the release of the accelerator is judged by the judging means.
