Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automobile driving characteristic switching device that switches the control characteristics of a plurality of driving assist devices such as a power steering device and an automatic transmission device according to instructions from a driver. It is something.

<Conventional technology> In recent years, many driving assistance devices such as power steering devices, automatic transmission devices, and suspensions have been electronically controlled in high-end cars, and their control characteristics can be changed according to the driver's preferences and driving conditions. It is now possible to do so.

<Problems to be Solved by the Invention> However, in such conventional devices, a characteristic changeover switch is provided for each driving assist device, and when it is desired to change the control characteristics, the changeover switch is operated for each device to control the device. Since the characteristics are changed, when changing the control characteristics of multiple driving assist devices at the same time, such as when moving from city driving to mountain road driving, multiple changeover switches must be sequentially changed, resulting in poor operability. There's a bad problem.

In addition, if there are many driving assist devices as described above, the driving characteristics may vary depending on how the control characteristics of each device are combined.
Since there are anywhere from 0 to several dozen combinations available, it is difficult to decide which combination to use when driving, and there is a problem in that the optimum combination of characteristics cannot be selected instantaneously.

<Means for Solving the Problems> FIG. 1 is an overall configuration diagram for clearly demonstrating the present invention. The present invention includes a setting storage means A for setting and storing control characteristics to be taken by each of a plurality of driving assist devices D1 to Dn corresponding to each of a plurality of driving characteristic modes, and a mode specifying switch B operated by a driver. In response to the output of the plurality of driving assist devices D1 in the specified characteristic mode.
The present invention is characterized by further comprising a control means C which reads control characteristics to be taken by Dn from the setting storage means A and supplies the read control characteristics to the plurality of driving assist devices.

<Operation> The driver determines the specific control that each of the plurality of driving assist devices D1 to Dn should take for each driving characteristic mode, and sets this in the setting storage means A.

After completing such settings, when the driver selects one of the driving characteristic modes using the mode designation switch B, the control means C sets the control characteristics of each device corresponding to the selected driving characteristic mode. A determination is made based on the settings, and a signal corresponding to the determination is output to each of the driving assist devices D1 to Dn. Thereby, the control characteristics of the plurality of traveling aid bags WDI to Dn are changed simultaneously according to the settings in the setting storage means.
