Problems solved by technology

However, showing fuel economy alone is not an adequate indicator of improved driving skills, because it is not known how drivers can specifically improve driving behavior to enhance fuel economy, and it is not known to what extent fuel economy can be further enhanced by improving driving behavior

Embodiment Construction

[0029] in the attached picture figure 1 is a block diagram showing the structure of the vehicle behavior evaluation system according to the present invention, and shows a case of application to a vehicle provided with a constant speed control device 10 such as an automatic cruise controller and an automatic transmission 27 with a torque converter 20 . The system includes: an on-vehicle unit 1 installed on a vehicle as an evaluation object, and a monitoring computer 2 for monitoring the vehicle.

[0030] The onboard unit 1 includes: a calculation unit 3 including a CPU, a memory, and an input / output interface; a display 4 such as an LCD; a memory card reader / recorder 5 ; and a built-in acceleration sensor 6 . The display 4 is installed in the vehicle at a position where the driver can easily view it.

[0031] The calculation unit 3 receives the vehicle speed (rotational speed of the driving wheel or transaxle) signal input by the vehicle, the rotational speed signal of the eng...

Abstract

A vehicle behavior assessment system includes: an automatic control device (10, 27) for setting a vehicle target behavior condition and controlling the vehicle to achieve the target behavior condition; and a display device (4) mounted on the vehicle. The system determines whether an operation that deteriorates the fuel economy is performed according to the operating condition of the vehicle; determines the operating status of the automatic control device (10, 27) according to the operating condition of the vehicle; , 27), calculating excess fuel consumption as the amount of fuel excessively consumed due to the operation deteriorating fuel economy; and displaying the calculated excess fuel consumption on the display device (4).

Description

technical field [0001] The present invention relates to systems for assessing fuel economy and other vehicle operating conditions. Background technique [0002] The fuel economy display device disclosed in JP2000-205925A published by the Japanese Patent Office in 2000 calculates the fuel consumption according to the fuel injection pulse signal output by the engine control unit, calculates the driving distance according to the vehicle speed pulse signal output by the vehicle speed sensor, and divides the calculated driving distance Calculates and displays fuel economy in terms of fuel consumption. However, showing fuel economy alone is not an adequate indicator of improved driving skills, because it is not known how drivers can specifically improve driving behavior to enhance fuel economy, and it is not known to what extent fuel economy can be further enhanced by improving driving behavior . Contents of the invention [0003] Miyama, inc proposes a vehicle evaluation syst...
