PURPOSE:To enhance the climbing ability of a motor vehicle while ensuring safety. CONSTITUTION:A current detector 4 is inserted into a control circuit and current supply is controlled such that the detected current does not exceed a limit level (I) being set for the purpose of protection of control machine and the limit level (I) is lowered when an inclination angle detector 5 detects a specific angle (alpha) which may cause trouble in safety traveling. Current is normally fed upto the limit level (I) which is set at a maximum level within safety range of the control machine thus realizing quick traveling. When a motor vehicle travels on a hill with the specific angle (alpha) which may cause trouble in safety traveling, the inclination angle detector 5 detects the fact and lowers the limit level (I) thus ensuring safety. |
