- ICE vehicle type
- regenerative braking is performed in which braking is performed by causing the electric motor to function as a generator during deceleration and converting the vehicle's kinetic energy into electric energy.
- the converted electric energy is stored in the battery and reused when accelerating. Therefore, the battery used in the hybrid vehicle is repeatedly discharged during running, such as at the car speed, and is recharged by regenerative braking during deceleration.
- the battery of a hybrid vehicle mounted as a power source has a life because it deteriorates with use. This is because the internal resistance of the battery increases and the charge / discharge capacity (battery capacity) of the cell gradually decreases due to long-term running. Therefore, the battery of the hybrid vehicle must be properly grasped.
- the vehicle specifications are related to the vehicle type of the vehicle, for example, year, vehicle weight, or equipment specifications.

- the capacity is reduced due to deterioration of the battery over time in the electric motor that should originally be the power source, and the gasoline engine automatically compensates for the decrease in capacity.
- the fuel consumption of gasoline is reduced because the engine runs with a smaller engine displacement than the passenger car of the same model.
- This reduction in fuel consumption of gasoline is more pronounced when driving at a constant speed, that is, when driving, such as cornering, lane change, start, and deceleration, than during normal driving.
- driving such as cornering, lane change, start, and deceleration
- the system is designed to make effective use of the power source by combining the gasoline engine and electric motor.

- the horizontal axis represents travel distance (km), and the vertical axis represents travel fuel consumption (kmZL).
- the mileage of the vehicle varies around an approximately constant value (al), but when the vehicle travels beyond a certain mileage (bl), battery deterioration begins and the fuel efficiency of the vehicle varies. It goes down.
- Driving with a hybrid system that is, the fuel efficiency value (al) when the gasoline engine and electric motor operate efficiently without battery deterioration, and the distance (bl) at that time, and the battery 16
- the fuel consumption value (a 2) and the distance traveled at that time (b 2) when the vehicle deteriorates and travels using only the gasoline engine are displayed.
- the travel fuel consumption measured for each degree of battery deterioration decreases from the value of a1 to the value of a2 as the mileage increases.
- the travel fuel consumption evaluation unit 12 extracts a travel fuel consumption decrease curve for each driving pattern from these measured values.
- the driving fuel consumption evaluation unit 12 determines the driving operation of the driving operator from the history of driving operation for each driving pattern transmitted from the data measuring unit 8 related to vehicle driving. That is, the actual driving fuel consumption data measured by the data measuring unit 8 relating to vehicle driving includes variations due to the driving operation of the driver. This variation is taken into account when judging the degree of battery deterioration by comparing with the above. For example, in the case of a beginner with respect to vehicle driving, generally, the driving operation with poor driving fuel consumption is based on the driving locus and driving speed history at cornering. This reduction in driving fuel consumption due to the driving operation is a different factor from the reduction in driving fuel consumption due to battery deterioration, so it must be excluded and evaluated.
- the travel fuel consumption evaluation unit 12 sets in advance the degree of decrease in travel fuel consumption due to the driving operation for each driving operation of the driver. For example, when the driving fuel consumption by driving operation (Champion de Overnight) by a person familiar with driving operation is set to 1.0, a variation in driving fuel consumption from 1.0 to 0.8 is set.
- the driving fuel consumption evaluation unit 1 2 is the difference in the driving fuel consumption variation from the history of driving operation in actual driving for each driving pattern.
- the actual driving fuel consumption data is compared with the test driving fuel consumption data that has been reduced by the reduction in driving fuel consumption due to the set driving operation.
- the actual travel fuel consumption data is compared with the test travel fuel consumption data, taking into account the degree of decrease in travel fuel consumption due to the driving operation set in the evening. As the driver's driving proficiency increases, the degree of decline gradually approaches 1.0.
- the travel fuel consumption evaluation unit 1 2 travels from the travel fuel consumption reduction curve for each driving pattern extracted from the test travel fuel consumption data based on the travel distance measured by the vehicle measurement unit 8 regarding vehicle travel. Evaluate the degree of fuel consumption reduction. Furthermore, from the history of driving operations for each driving pattern measured by the data evening measurement unit 8 relating to vehicle driving, the driving operation of the driver is determined, and the driving The degree of decrease in driving fuel consumption due to battery deterioration is calculated in consideration of the decrease in driving fuel efficiency due to battery. When the degree of decrease in driving fuel consumption due to battery deterioration exceeds the set value, the warning message is displayed on the first display means as described above in the energy monitor —screen 3 4 0 or hybrid system configuration screen. 4 4 0 is displayed.
- This warning message may be judged with reference to multiple past records of the operation pattern in order to improve accuracy.
- the second display means displays the driving fuel consumption for the driving pattern 5 4 2 and the past average driving fuel consumption for the driving pattern 5 4 3 and the past highest driving fuel consumption display 5 4 4 is displayed side by side on the driving pattern fuel consumption information screen 5 4 0.
- the degree of decrease in driving fuel consumption due to battery deterioration may be shown on the driving pattern fuel consumption information screen 540.
- the test driving fuel consumption data for the driving pattern (champion overnight) may be displayed side by side.
