Recently, a Haval H6 drove from Zhuzhou, Hunan along the Beijing-Hong Kong-Macao Expressway to Qingyuan, Guangdong. After running more than 500 kilometers, it was stopped due to exhaustion of fuel. According to the driver, the vehicle could not be lifted due to the cruising speed, causing the vehicle to lose control.
Tianmu News reporter called the official hotline of Great Wall Haval. Customer service said that he has not received any feedback on the inability to resolve the related issues of cruise control. If there is an emergency in the vehicle, you can contact the 24-hour rescue customer service and after-sales store to deal with it.
Senior car maintenance technician Gong Menghui told Tianmu News reporters that before the accident identification was found, it was difficult to easily judge the reason for the Haval H6 vehicle to lose control. "Among all the instructions of the automotive ECU (electronic control unit), the brake has the highest priority. As long as the brake pedal is pressed, other functions must give way."
Gong Menghui analyzed that the brake system and cruise control system are two independent control units, and the possibility of both failure is not high. The relevant departments should conduct further investigations to restore the real cause of the accident.
In fact, according to public reports, models of multiple brands have caused the vehicle to lose control due to cruising speed. So, why did cruising speed accidents happen repeatedly?
It is understood that the cruise control system is a system that uses electronic control technology to keep the car moving automatically and at a constant speed. Generally speaking, when the driver is driving in an open section such as a highway, the vehicle's speed is locked by pressing the buttons, and the vehicle can be automatically maintained at a fixed speed without stepping on the accelerator pedal.
It is understood that, including models under 100,000 yuan, almost all mid-to-high-end models on sale are equipped with cruise control systems, and some even all models of the entire series are equipped, which is a relatively popular vehicle automation function.
Tianmu News reporter randomly asked several car owners, and most of them said that the car has a cruise control function and is frequently used during long-distance travel.
"When I drive the highway, if the road is not so congested, I like to use the cruise control function, which can free my feet and relieve driving fatigue." Mr. Zhang usually drives a Japanese SUV and likes to use the cruise control function when traveling long distances.
It is worth noting that there have been cases of accidents caused by the start of cruise control, and the reason is due to external forces.
In October this year, a vehicle in the Shaoxing section of Changtai Expressway in Zhejiang Province suffered a cruising speed function failure. After the 4S store inspected the vehicle, it was found that there was a white stain behind the button that controlled the cruising speed, which may be the main cause of the failure. The owner recalled that 10 days before the incident, he accidentally knocked over the steering wheel while drinking milk tea in the car.
Automobile industry analyst , visiting professor Zhang Xiang, Huanghe Academy of Sciences , in an interview with Tianmu News reporter, said that the degree of electronicization of cars is getting higher and higher, and damage to vehicle components should be avoided. "Many vehicle handrail boxes contain some automotive electronic modules hidden in the position. If tea is sprinkled on it, it may damage the electronic module below, causing vehicle failure."
Gong Menghui suggested that in case of a vehicle out of control, the steering wheel should be controlled first and the double flash should be turned on, and then try to step on the brake, hang neutral, and force out the engine to reduce the speed. If none of the above methods work, you should call the brand, traffic police, etc. for help.
