Example Embodiment

[0062] Now, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0063] figure 1 It is a circuit block diagram of a slope detection device according to an embodiment of the present invention. The slope detection device mainly includes a CPU 1 , an EEPROM 2 and an atmospheric pressure sensor 3 . The CPU 1 is a control section that generally controls all operations of the slope detection device. Also, the CPU 1 functions as a height calculation section, a gradient calculation section, a count section, and a slope determination section. The EEPROM 2 stores programs for operating the CPU 1 or data for measurement. The atmospheric pressure sensor 3 measures the atmospheric pressure P around the running vehicle at predetermined time intervals. In this embodiment, the atmospheric pressure is measured at intervals of about 0.5 seconds to store the data of the past prescribed number of times as the altitude value H, w...

Abstract

The present invention discloses a slope detection method and a slope detector. The slope detector comprises an atmosphere sensor and a control part. The control part confirms whether the driving rod of the vehicle is a slope according to the atmosphere data input from the atmosphere sensor. The control part comprises the following components: a height calculation part which calculates the height according to the atmosphere data obtained from the atmosphere sensor each time the vehicle is driven for a preset unit driving distance; a slope gradient calculation part which calculates the slope gradient of the road according to the difference between the height calculated last time and the height calculated this time and the unit driving distance; a counting part which counts the time of slopegradient calculation; and a slope confirming part which confirms that the road is a slope when the slope gradients obtained by the slope gradient calculation part are continuously in a preset range in the preset number of times.

Description

technical field [0001] The present invention relates to a slope detection method and a slope detection device which provide slope information for traffic control of vehicles such as trucks. Background technique [0002] Economical driving of motor vehicles is considered to be important from the standpoint of environmental protection or affected by the recent sudden rise in fuel costs. In particular, the transportation industry whose work is carried by trucks etc. performs strict traffic control that pursues driving distance or fuel consumption to force drivers to perform energy-saving driving and save money. Furthermore, it has also been proposed that a traffic control system detects an uneconomical driving state such as sudden acceleration or engine overspeed, and notifies the driver of such driving state with an alarm. [0003] In normal traffic control, in order to drive with low fuel cost, an upper limit is usually set so that the rotation speed of the engine does not e...
