摘要:
A control unit for controlling an automobile has a one-chip microcomputer including an internal memory (2) for storing an operating program and an application program. An external memory (7) is connected to the one-chip microcomputer which stores an additional application program. By such an expedient the one-chip computer can be readily installed in another type of automobile thereby eliminating the necessity of development of an updated application program in the one-chip microcomputer. In a further aspect of this invention, a control unit for an automobile has a one-chip microcomputer including a cache memory (19) and an internal memory (2) which stores an operating system program and an application program. An external memory (7) is connected to the one-chip microcomputer for storing an additional application program whereby the additional application program stored in the external memory (7) is fetched into the cache memory (19) for execution. Such an arrangement has the advantage of real time processing.

The invention relates to a vehicle speed control apparatus for allowing a host vehicle (1) trailing a preceding vehicle (2) to accelerate and decelerate without causing discomfort to the host vehicle driver. While the host vehicle (1) is trailing the preceding vehicle (2), the apparatus on board the host vehicle (1) stores the speed of the preceding vehicle (2) entering a curve ahead as well as a headway distance of the host vehicle (1) to the preceding vehicle (2). Upon reaching the curve, the host vehicle (1) is controlled by the apparatus to enter the curve at a speed not in excess of the stored speed of the preceding vehicle (2).

In a vehicle running control apparatus and method, the change of a difference in frequency between an electromagnetic wave signal transmitted from a vehicle (A) and an electromagnetic wave signal reflected from an object (B) is detected (301). Information inclusive of a distance (D m ) between the object and the vehicle and a relative speed (V r ) of one of the object and the vehicle to the other is generated (205, 210) on the basis of the change in frequency difference. A desired speed (V d , ΔV d ) is generated (405, 503) on the basis of the generated information and information (V o ) of the running of the vehicle so that the change in frequency difference is generated. A signal for control of the speed (V o ) of the vehicle is generated (209) on the basis of the desired speed.
摘要:
An apparatus and a method for controlling an automotive vehicle are disclosed, in which a control amount for securing safety of the vehicle and the control amount for achieving a state intended for by the driver of the vehicle are switched in such a manner as to reduce the shock due to the change in the torque generated from the power train, thereby accomplishing both safety and maneuverability at the same time. A first target value is set for controlling at least selected one of the driving torque, the driving force and the acceleration/deceleration rate. A second target value is calculated in accordance with the drive mode intended for by the driver or the driving environment ahead of the vehicle. In the case where a deviation exceeding a predetermined value develops between the first target value and the second target value, the fluctuations of at least one of the driving torque, the driving force and the acceleration/deceleration rate are suppressed.

The invention relates to a power transmission apparatus for use in an automobile, including a gear-type transmission and plural numbers of motors, the gear-type transmission (100) comprises: a first input shaft (23), onto which the motive power is transmitted from an engine (1) through a first friction clutch (25); a second input shaft (24), onto which the motive power is transmitted from an engine (1) through a second friction clutch (26); and plural numbers of gear trains (31-42) between the first input shaft (23) and an output shaft (27), and between the second input shaft (24) and the output shaft (27). Onto the first input shaft (23) and the second input shaft (24) are connected a first motor (29) and a second motor (30), so that the motive power is transmitted from the above two motors through the plural numbers of gear trains (31-42) up to the output shaft (27). Therefore, it is possible to make the maximum torque of the motors small, which is required when changing claw clutches provided on the gear trains (31-42).
