Claim 3:
4. A driving assistance system for a driver who operates a vehicle on a chassis dynamometer in mode driving that performs operations, including at least acceleration and deceleration, on the vehicle to follow a driving pattern including variation of traveling speed of the vehicle with time, the driving assistance system comprising:
a first sensor configured to detect operation amount of an acceleration pedal, of the vehicle, operated by a driver who operates the vehicle;
a second sensor configured to detect brake hydraulic pressure by operating a brake pedal operation of the driver;
a display unit; and
a controller coupled with the first sensor, the second sensor and the display unit, and the controller configured to display, in time series on the display unit,
the driving pattern,
traveling speed measured by the chassis dynamometer,
target operation amount, calculated in advance, of the acceleration pedal to follow the driving pattern, and
operation amount of the acceleration pedal operated by the driver, the operation amount detected by the first sensor, and
target brake hydraulic pressure, calculated in advance, to follow the driving pattern, and
hydraulic pressure by operating a brake pedal operation of the driver, the hydraulic pressure detected by the second sensor, wherein

the target operation amount is an accelerator opening degree configured to adjust the traveling speed measured by the chassis dynamometer to the driving pattern by using a driving force calculated from
a traveling resistance provided from the chassis dynamometer and
an acceleration with a response delay from when an accelerator pedal is operated to when the traveling speed is accelerated, and

the target brake hydraulic pressure is a brake hydraulic pressure configured to adjust the traveling speed measured by the chassis dynamometer to a 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.
