Abstract

A mode driving assistance system for a vehicle assists a driver when the driver conducts mode driving by operating an operation member such that a traveling speed meets a time series change in the traveling speed. The operation member is disposed on a chassis dynamometer. The operation member conducts at least one of acceleration or deceleration of the vehicle. The system includes: a display that the driver can observe visually; a storage that stores a target value relating to an operation amount of the operation member in time series; a first detector that detects an actual value of the operation amount of the operation member; and a controller that displays 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.

Dependent claims

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.

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.
