What does BMW ACC mean?

BMW ACC stands for Adaptive Cruise Control. Here are the specific details: 1. Adaptive Cruise Control System: The Adaptive Cruise Control system is an intelligent automatic control system developed from the existing cruise control technology. During vehicle operation, a distance sensor (radar) installed at the front of the vehicle continuously scans the road ahead, while wheel speed sensors collect speed signals. 2. Function: When the distance to the vehicle ahead becomes too small, the ACC control unit can coordinate with the anti-lock braking system and engine control system to apply appropriate braking to the wheels and reduce engine output power, ensuring the vehicle maintains a safe distance from the vehicle ahead. When controlling vehicle braking, the Adaptive Cruise Control system typically limits the deceleration to a level that does not affect comfort. If greater deceleration is required, the ACC control unit will issue audible and visual signals to prompt the driver to take active braking measures. When the distance to the vehicle ahead increases to a safe distance, the ACC control unit resumes control of the vehicle at the set speed.

What to Do When the Car Doesn't Shut Off After a Jump Start?

Generally, this situation occurs because the car's starting current hasn't been fully charged, requiring additional jump-start time. Here's relevant information: 1. Typically, a jump start of 10 to 20 minutes is needed to charge the car battery sufficiently for starting, after which the battery can recharge itself while running. When a car battery is dead and can't provide starting current to the engine, connecting it to another vehicle's battery for a jump start is the solution. 2. A jump start, also known as a boost or jump, involves connecting another vehicle's battery or an external power source to a car with a depleted starting battery to start the vehicle. Once the vehicle starts, its normal charging system can recharge the battery, allowing the auxiliary power source to be removed. As long as the vehicle's charging system is functioning properly, a normally running vehicle will restore the battery's charge.

Why Are Joint Venture Cars More Expensive Than Domestic Cars?

Joint venture cars are more expensive than domestic cars for the following reasons: 1. Joint venture cars incur many additional costs compared to domestic cars. For example, brand usage fees, patent royalties, etc. These costs increase the overall expenses of joint venture cars. 2. Joint venture cars have dominated the domestic market for many years, with a high market share and relatively better reputation, leading to generally higher pricing. 3. Technical aspects. It must be admitted that joint venture cars do perform better in many technical areas compared to domestic cars. Domestic cars are still in the exploration phase, with relatively less advanced technology. In such cases, domestic cars can only compete on cost-performance, naturally resulting in lower prices than their joint venture counterparts in the same segment. 4. Supply and demand determine the value of the product itself. For example: if there are only one or two potential buyers for a domestic car but five or six for a joint venture car, the price of the joint venture car will inevitably be higher.
