1. A mode driving assistance system for a driver who operates a vehicle on a chassis dynamometer wherein the driver conducts mode driving by operating an operation member such that a traveling speed measured by the chassis dynamometer meets a target traveling speed set in advance that changes in a time series, the operation member being configured to conduct at least one of acceleration or deceleration of the vehicle, the mode driving assistance system comprising:
a display unit;
a storage configured to store a target value relating to an operation amount of the operation member in time series, the target value being set in advance in order to attain the time series change in the target traveling speed;
a first detector configured to detect an actual value of the operation amount of the operation member; and
a controller configured to display
the target traveling speed,
the traveling speed measured by the chassis dynamometer,
the target value of the operation amount of the operation member stored in the storage and
the actual value of the operation amount of the operation member detected by the first detector, as a time series image on the display unit,
wherein
the operation member is configured to decelerate the vehicle and comprises a brake pedal,
the operation amount of the operation member is a brake hydraulic pressure in accordance with a depression amount of the brake pedal, and
the target value is a brake hydraulic pressure configured to adjust the traveling speed measured by the chassis dynamometer to the target traveling speed by using a braking force calculated from
a traveling resistance provided from the chassis dynamometer and
a deceleration with a response delay from when the brake pedal is operated to when the traveling speed is decelerated.
 
3. The mode driving assistance system for a vehicle according to claim 1, wherein
the controller comprises
a correction unit configured to, when the actual value of the operation amount of the operation member is within a predetermined range that is set in advance to the target values of the operation amount of the operation member and the actual value of the traveling speed is out of a predetermined range that is set in advance relative to the target values of the traveling speed, correct the target value of the operation amount of the operation member in accordance with a deviation amount between the actual value of the traveling speed and the target value of the traveling speed.
