Abstract: A display controller calculates a driver-related fuel economy value and a performance value indicating an amount of difference between the calculated driver-related fuel economy value and a baseline value. The display controller displays the performance value on a display device during vehicle operation. A memory in the vehicle stores a number of initial fuel economy values that are replaced by the driver-related fuel economy values as new driver-related fuel economy values are calculated. An oldest fuel mileage value stored in the memory is replaced with a newly calculated fuel mileage. The baseline value used to calculate the performance value is an average of the number of the fuel economy values stored in the memory.

Abstract: A high-pressure pump has an elastic member arranged in a damper chamber between a first diaphragm and a second diaphragm. The elastic member is always in contact with both diaphragms while the high-pressure pump is operated. When the diaphragms are further vibrated due to a resonance under a situation where a frequency of the pressure pulsation of low-pressure fuel is in agreement with the characteristic frequency of the diaphragms, the elastic member restricts the deformation of the diaphragms. Therefore, the resonance of the first diaphragm and the second diaphragm can be restricted.

Abstract: In an electronic control unit, an important process includes several instructions that are successively executed and contain no branch instruction. Each of the instructions is stored in each of storage areas of memory according to an execution sequence. The storage areas are respectively assigned addresses that vary in increments of a specified value according to the execution sequence. The important process stores, in an expected value counter, a value of a program counter when control transitions to the important process. If a comparison result indicates a difference between the value of the program counter and a value of the expected value counter, an occurrence of an error is determined.
